C nanotubes (CNTs) have unusual phys. properties that are valuable for nanotechnol. and electronics, but the chem. synthesis of chirality- and diameter-specific CNTs and π-conjugated CNT segments is still a great challenge. Reported here are the selective syntheses, isolations, characterizations, and photophys. properties of 2 novel chiral conjugated macrocycles ([4]cyclo-2,6-anthracene; [4]CAn2,6), as (-)/(+)(12,4) C nanotube segments. These conjugated macrocyclic mols. were obtained using a bottom-up assembly approach and subsequent reductive elimination reaction. The hoop-shaped mols. can be directly viewed by a STM technique. Chiral enantiomers with (-)/(+) helicity of the [4]CAn2,6 were isolated by HPLC. The new tubular CNT segments exhibit large absorption and luminescence red shifts compared to the monomer unit. The C enantiomers also show strong circularly polarized luminescence (glum≈0.1). The results reported here expand the scope of materials design for bottom-up synthesis of chiral macrocycles and enrich existing knowledge of their optoelectronic properties.

Electric Literature of C8H12Cl2Pt. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Dichloro(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12Cl2Pt, CAS is 12080-32-9, about Synthesis and catalytic performance of highly dispersed platinum nanoparticles supported on alumina via supercritical fluid deposition. Author is Jiang, Haoxi; Yao, Chuanxu; Wang, Yaodong; Zhang, Minhua.

Highly dispersed platinum nanoparticles (NPs) supported on alumina were prepared by supercritical fluid deposition (SFD) with the aid of co-solvent ethanol using inorganometallic Na2PtCl6·6H2O as Pt precursor. The mean Pt particle size (1.5 nm) was obtained at the optimized deposition conditions of 40°C and 110 bar and 3 h of deposition time. The catalysts were characterized by high-resolution transmission electron microscopy (HR-TEM), X-ray diffraction (XRD), CO diffuse reflectance IR Fourier transform spectroscopy (CO-DRIFTS), XPS, inductively coupled plasma optical emission spectrometry (ICP-OES) and hydrogen-oxygen titrations to investigate the structure-activity relationship. Compared with the catalyst prepared via an impregnation method, the Pt was highly dispersed to smaller particles for Pt/Al2O3 catalysts prepared by SFD and showed much higher catalytic activity of catalytic reforming of cyclohexane dehydrogenation.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Classics Meet Classics: Theoretical and Experimental Studies of Halogen Bonding in Adducts of Platinum(II) 1,5-Cyclooctadiene Halide Complexes with Diiodine, Iodoform, and 1,4-Diiodotetrafluorobenzene, published in 2021-02-03, which mentions a compound: 12080-32-9, mainly applied to halogen bonding platinum cyclooctadiene halide complex diiodine iodoform diiodotetrafluorobenzene; safety cyclooctadiene health hazard, Safety of Dichloro(1,5-cyclooctadiene)platinum(II).

Complexes of PtX2COD (X = Cl, Br, I; COD = 1,5-cyclooctadiene) were cocrystd. with classical halogen-bond donors (CHI3, I2, and 1,4-diiodotetrafluorobenzene (FIB)), resulting in noncovalently bound supramol. aggregates of various lengths-from heterotrimers to polymers. The influence of halides in the complexes on the geometry and strength of the halogen bond (XB) was studied both exptl. by single-crystal XRD and theor. by quantum chem. methods such as noncovalent interaction plots (NCI-plot), electrostatic potential (ESP) surface anal., and a combination of electron localization function (ELF) and quantum theory of atoms in mols. (QTAIM) analyses. It was shown that strength of XB interactions in the adducts increases in the order CHI3 > FIB > I2. Although halogen bonding was found to be the main preorganizing force in the structures, in the case of FIB adducts a rare Pt···I interaction was involved in addnl. stabilization of the structure. Hence, fine-tuning of halogen bonding can influence the length of the polymer, as well as the strength and directionality of interactions in the adduct. Since Hassel’s already classical work on charge-transfer interactions, halogen bonding has attracted a great deal of attention as a potentially useful instrument to organize mols. Due to the tunability, relative strength, and directionality, halogen bonding has been used as a self-assembly tool in crystal engineering. In this study classics meet classics: classical halogen bond donors XBD (such as mol. iodine, iodoform, and FIB) and classical synthons PtX2COD were used to create metallopolymeric adducts. In the obtained systems the XBD influenced the geometry (1D or 2D) and the length (heterotrimer or polymer) of the adduct. To understand differences among the obtained systems, they were further studied with computational methods, and addnl. stabilizing weak interactions were discovered. Caution: COD is hazardous to health and should be handled with care.

Five Pt(II) complexes are described in which the metal ion is bound to anionic N N N-coordinating ligands. The central, deprotonated N atom is derived from an imide Ar-C(:O)-NH-C(:O)-Ar {PtL1-2Cl; Ar = pyridine or pyrimidine}, an amide py-C(:O)-NH-CH2-py {PtL3Cl}, or a hydrazide py-C(:O)-NH-N:CH-py {PtL4Cl}. The imide complexes PtL1-2Cl show no significant emission in solution but are modestly bright green/yellow phosphors in the solid state. PtL3Cl is weakly phosphorescent. PtL4Cl is formed as a mixture of isomers, bound through either the amido or imino nitrogen, the latter converting to the former upon absorption of light. Remarkably, the imino form displays fluorescence in solution, λ0,0=535 nm, whereas the amido shows phosphorescence, λ0,0=624 nm, τ=440 ns. It is highly unusual for two isomeric compounds to display emission from states of different spin multiplicity. The amido-bound PtL4Cl can act as a bidentate O N-coordinating ligand, demonstrated by the formation of bimetallic complexes with iridium(III) or ruthenium(II).

Category: alcohols-buliding-blocks. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: Dichloro(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12Cl2Pt, CAS is 12080-32-9, about Sterically Encumbered 4,5-Bis(diphenylphosphino)acenaphthene Ligand and Its Ni(II), Pd(II), Pt(II), and Cu(I) Complexes. Author is Tosolini, Massimo; Avo, Joao; Parola, Antonio Jorge; Balducci, Gabriele; Tecilla, Paolo.

A new sterically encumbered sym. substituted 4,5-bis(diphenylphosphino)acenaphthene ligand (L) has been prepared The ligand readily forms distorted square-planar complexes with group 10 metal ions [Ni(II), Pd(II), Pt(II)] and a dimeric tetrahedral complex with Cu(I). The x-ray structures of the ligand and of the complexes show a notably short distance between the two phosphorus atoms, well below than twice the van der Waals radius of P, due to the steric requirements of the rigid acenaphthene backbone. Moreover, in the complexes a stabilizing π-π interaction between two Ph rings belonging to the two P atoms is present. The [LCuCl]2 complex is weakly fluorescent both in solution and in the solid state with higher quantum yield as a solid where it exhibits thermally-activated delayed fluorescence and phosphorescence. [LPdCl2] and [LCuCl]2 behave as chloride transporters across a liposomal phospholipid membrane with the Pd(II) complex displaying a very high activity.

SDS of cas: 12080-32-9. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: Dichloro(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12Cl2Pt, CAS is 12080-32-9, about Water’s Role in Polymorphic Platinum(II) Complexes.

Solvent plays a vital role in the recrystallization process and resulting crystallinity of materials. This role is of such importance that it can control the stability and utility of materials. In this work, the inclusion of a solvent in the crystalline lattice, specifically water, drastically affects the overall stability of two platinum polymorphs. [Pt(tpy)Cl]BF4 (tpy = 2,2′;6’2”-terpyridine) crystallizes in three forms, red (1R) and blue (1B) polymorphs and a yellow nonsolvated form (2). 1R is the more stable of the two polymorphs, whereas 1B loses crystallinity upon dehydration at ambient conditions resulting in the formation of 2. Close examination of the solid-state extended structures of the two polymorphs reveals that 1R has a lattice arrangement that is more conducive to stronger intermol. interactions compared to 1B, thereby promoting greater stability. In addition, these two polymorphs exhibit unique vapochromic responses when exposed to various solvents.
