Abstract

AbstractA series of block copolymers were prepared consisting of a block of poly(styrene) and a block in which a mesogenic group was attached by polymer analogous chemistry to a flexible backbone. Two types of mesogenic groups which produced a range of mesophases were investigated: (i) an azobenzene mesogenic group and (ii) a semifluorinated group. Organization caused by liquid crystallinity and phase separation leads to simultaneous organization on a variety of length scales. Comparison of the ordering behavior of these two types of mesogenic groups and more conventional flexible chain diblocks are made.
