Narrow band gap conjugated polymer zwitterions (CPZs) were synthesized by Suzuki polymerization and characterized to understand their electronic properties and utility as cathode modification layers in solar cells. The polymers were prepared from diketopyrrolopyrrole (DPP) and iso-indigo monomers containing sulfobetaine (SB) pendant groups, benefiting from an ion-rich aqueous phase in the polymerizations UV-vis absorption spectroscopy revealed the optical energy gap value for the CPZs, ranging from 1.7 to 1.2 eV. UPS of the CPZs as thin layers on Ag metal showed that the pendent zwitterions impart an interfacial dipole (Δ) to the metal and a work function reduction of ∼0.9 eV. OPVs fabricated using a conventional bulk heterojunction (BHJ) device architecture of ITO/PEDOT:PSS/(PTB7:PC₇₁BM)/CPZ/Ag led to dramatic improvements in power conversion efficiency (PCE) values relative to devices having bare Ag cathodes (PCE < 2% for bare Ag vs. 6.7-7.7% for CPZ/Ag). The benzothiadiazole (BT)/DPP polymer denoted as PT2BTDPPSB gave an optimal PCE of 7.7% in a conventional BHJ OPV device architecture fabricated on a Ag cathode. © 2014 Wiley Periodicals, Inc. J.

The synthesis of a 2-monobrominated dithieno[3,2-b:2′,3′-d]phosphole has opened the access to a series of highly luminescent π-conjugated oligomers that link two dithienophosphole units via a variety of aromatic spacers. The nature of the linking mode was found to have a significant impact on the photophys. properties of the system as a whole, either considerably improving the molar absorptivity of the new extended chromophores, or providing luminescent materials with red-shifted emission features and substantial photoluminescence quantum yields.

Li, Yaowen published the artcileNovel low-bandgap oligothiophene-based donor-acceptor alternating conjugated copolymers: synthesis, properties, and photovoltaic applications, Related Products of alcohols-buliding-blocks, the publication is Journal of Polymer Science, Part A: Polymer Chemistry (2010), 48(13), 2765-2776, database is CAplus.

A series of novel soluble donor-acceptor low-bandgap-conjugated polymers consisting of different oligothiophene (OTh) coupled to electron-accepting moiety 2-pyran-4-ylidenemalononitrile (PM)-based unit were synthesized by Stille or Suzuki coupling polymerization The combination of electron-accepting PM building block with varied OTh_n (the number of thiophene unit increases from 3 to 5) results in enhanced π-π stacking in solid state and intramol. charge transfer (ICT) transition, which lead to an extension of the absorption spectra of the copolymers. Cyclic voltammetry measurements and MO distribution calculations indicate that the highest occupied MOs (HOMO) energy levels could be fine-tuned by changing the number of thiophene units of the copolymers, and the resulting copolymers possessed relatively low HOMO energy levels promising good air stability and high-open circuit voltage (V_oc) for photovoltaic application. Bulk heterojunction photovoltaic devices were fabricated by using the copolymers as donors and (6,6)-Ph C₆₁-butyric acid Me ester as acceptor. The highest V_oc reached 0.94 V, and the short circuit currents (J_sc) were improved from 1.78 to 2.54 mA/cm², though the power conversion efficiencies of the devices were measured between 0.61 and 0.99% under simulated AM 1.5 solar irradiation of 100 mW/cm², which indicated that this series copolymers can be promising candidates for the photovoltaic applications.

Zhang, Chao published the artcileSynthesis, chiroptical properties, and self-assembled nanoparticles of chiral conjugated polymers based on optically stable helical aromatic esters, Product Details of C20H28B2O4S2, the publication is RSC Advances (2018), 8(2), 1014-1021, database is CAplus and MEDLINE.

By Suzuki coupling reaction, three pairs of chiral conjugated polymers with optically stable helical aromatic ester subunits as the main-chain were designed and synthesized. Polymers (+)-P-P1 and (-)-M-P1, (+)-P-P2 and (-)-M-P2 showed strong fluorescence emission, strong mirror image CD and circularly polarized luminescence (CPL) signals in THF. For polymers (+)-P-P3 and (-)-M-P3, containing the tetraphenylethene (TPE) moiety, they not only showed obvious aggregation induced enhancement emission (AIEE), but also exhibited mirror image CD signals and aggregation-induced enhancement CPL signals in THF-water mixtures Moreover, (+)-P-P3 and (-)-M-P3 could also form chiral nanoparticles by solvent evaporation induced self-assembly. Interestingly, it was further found that the size of the nanoparticles could be controlled by the changing of THF/water ratio, and their CPL properties were also shown.

In order to develop conjugated polymers with low band gaps and deep HOMO levels, copolymers consisting of alternating dodecyl thieno[3,4-b]thiophene-2-carboxylate and one (DTT-T₁) or two thiophene rings (DTT-T₂) were synthesized. The estimated optical band gap and HOMO level of DTT-T₁ and DTT-T₂ were ∼1.58/1.61 and ∼-5.15/-5.20 eV, resp., indicating that the polymers have relatively low band gaps and deep HOMO levels, as compared to many other reported polymers. Photovoltaic devices were fabricated using DTT-T₂ and a fullerene derivative (PCBM), and whose power conversion efficiency was 0.21% under the illumination of AM 1.5 (100 mW/cm²). The low conversion efficiency of the devices was attributed to the inefficiency of exciton formation due to the low absorption coefficient and self-quenching of the polymer and the un-optimized device conditions.

Park, Hyeonjung published the artcileDisintegrable n-Type Electroactive Terpolymers for High-Performance, Transient Organic Electronics, Category: alcohols-buliding-blocks, the publication is Advanced Functional Materials (2022), 32(2), 2106977, database is CAplus.

Degradable organic semiconductors have significant potential for transient and biomedical organic electronics, but there have been only a few studies on fully degradable conjugated polymers (CPs) that achieve high elec. performance. In addition, these examples are limited to p-type CPs. In this study, a series of fully degradable n-type CPs, naphthalene diimide (NDI)-based terpolymer (PNDIT2/IM-f) are developed. The incorporation of an imine linker (IM) into the CP backbone affords the capability of facile hydrolysis degradation while maintaining efficient π-conjugations and excellent elec. properties. An addnl. benefit of this mol. design is the systematic tunability of the degradation characteristics and elec. performance depending on the IM content (f_IM). At the optimal point (f_IM = 0.45) that enables complete degradation of the polymer under acidic conditions, the resulting PNDIT2/IM-0.45 film exhibits high electron mobility (μ_e) of 0.04 cm² V^-1 s^-1 in organic field-effect transistors (OFETs), demonstrating excellent potential as transient OFETs. The high μe value is mainly attributed to the enlarged edge-on orientations and tighter stacking of PNDIT2/IM-f crystallites as increasing f_IM. Thus, this study provides useful guidelines for the design of fully degradable n-type CPs and establishes an important correlation between the mol. structure-electronic performance-transient properties.
