A new series of liquid crystalline (LC) homopoloymers of poly {11-[4-(4-butylphenylazo)-phenoxyl-undecy] methacrytate} and their block-copolymers with polystyrene were synthesized by using atom transfer radical polymerization (ATRP)method. Thermal propertics were investigated by using DSC, X-ray diffraction and polarized phases. Nanostructures in the range of 20〜40nm were observed by using TEM, SAXS, and AFM. Different chromophore aggregation and photo-chemical behabiors between anncaled block copolymer and homopolymer films were observed, which might be attributed to microphase separation in the block copolymer thim films.
