Azobenzene functionalized polyelectrolytes and polyamphiphiles are novel functional polymers with many interesting characteristics such as the photo-responsive properties based on the photo-induced cis-trans isomerization, the ability to build up ordered supramolecular structure, and the sensitivity to the environmental stimuli. The aim of this dissertation is to investigate the rules that control the formation of ordered structures from the azo polyelectrolytes and polyamphiphiles based on the supramolecular interaction, to explore the relationships between the material functionality and the supramolecular self-assembled structures at different levels, and to establish the methods for producing novel materials with potential applications in photonic and electronic areas.

This study demonstrates optically and spatially band-tunable color cone lasers based on DDCLC cells with a photoisomerizable chiral dopant. The band-tunability is attributable to the recovery of the helix of the CLC resulted from the trans-cis isomerization induced decrease of the helical twisting power of the chiral dopant.The more the chiral cis-isomers are produced, the larger the tuned lasing band is.

本文主要藉由在胆固醇液晶射中加入可光致同素构化亲手性材，使胆固醇液晶所输出的彩色锥角射波段可光调控及空间调控，其射输出波段可调控的机制是由於当同素构化反应产生后，光致同素构化亲手性材的HTP值低并造成胆固醇液晶距改变，藉此间接调控输出的射波长，同素构化的程愈高，胆固醇液晶所输出的彩色锥角射波段可调控范围也愈大。
