摘要

Control of stereoregularity and optical activity of polymers has been a challenging theme in the field of material synthesis. Optical activity can be observed only in chiral molecules both in low and high molecular weight compounds. The influence of chiral units on supramolecular structures and possible applications of such molecules in areas such as catalysis, (bio)sensor research, optical devices etc. are thus worth studying. Polysilanes are interesting class of compounds with novel photoluminescence, semiconducting, photoconducting, thermochromic and nonlinear optical properties originated from delocalized electronic state derived from σ-conjugated Si-Si bonds. Polysilane dendrimers with their expected robust structures should be superior to linear systems in the application of conductive and nonlinear optical properties. Until now, polysilane dendrimers were reported by many groups, all of which had the hyper-methylated dendritic structure except for the structure with phenylene group as intermediate building block for chlorination.
