Abstract
In this Chapter, we have reviewed the recent research progress in the side-chain liquid crystalline polymers (LCPs) of both rod-like and disc-like types mainly based on typical azobenzene (AZO) calamitic mesogens with photoresponsive characteristics and triphenylene (TP) derivatives discotic mesogens. Side-chain liquid crystalline homopolymers and block copolymers prepared by typical controlled radical polymerization (CRP) techniques such as atom transfer radical polymerization (ATRP) and reversible addition-fragmentation chain-transfer (RAFT) are the primary systems to be introduced, together with the linear–dendritic liquid crystalline block copolymers with side-chain type dendritic liquid crystalline segments synthesized through iterative reactions. The phase behaviors and hierarchical structure evolution characterized by a combination of various techniques such as DSC, POM, SAXS/WAXS, TEM and AFM have been summarized and concisely commented. The relationship between the phase structures and morphologies and their optoelectronic properties has also been briefly discussed.
