Unidirectional assembly of 0D nanoparticles in a controlled manner is still a challenging task because of the intrinsic geometrically isotropic structure of 0D particles. Herein, we show that geometrically anisotropic 1D rod-shaped polymers facilitate the unidirectional assembly of clusters of 0D nanoparticles. Systematic investigations were performed using poly(Ph isocyanide) (PPI) as a well-defined 1D anisotropic rod-shaped polymer and fullerene C60 as a model crystalline 0D small organic mol. We demonstrated that high-aspect-ratio PPIs with non-branched alkyl side chains facilitated the 1D assembly of C60 crystals into ultralong whiskers and fibers exceeding 1 mm length with a diameter of ca. 1 μm, where the C60 crystals were phase separated from PPI and solvent mols. by a solution-drying process. Our methodol. was also applicable to other small organic building blocks like fullerene C70, 5,6,11,12-tetraphenylnaphthacene, tetraphenylethylene, and tetraphenylporphyrin to afford 1D mol. assemblies such as elongated whiskers, fibers, and dendritic structures. Furthermore, the addition of inorganic superparamagnetic iron-oxide nanoparticles (FeNP) into C60 toluene solution resulted in the formation of highly anisotropic FeNP cluster assemblies along the ultralong C60 fibers. We propose that the anisotropic depletion effect and the interfacial capillary force on the solution-drying process are the key factors for highly anisotropic assemblies of nanoparticle clusters. Since PPIs are readily modified, we believe that this study will pave a new way in the field of more functional rod-shaped polymers and creation of hierarchical crystalline materials. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Category: alcohols-buliding-blocks).
3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Category: alcohols-buliding-blocks
