Photoconductive organic materials have attracted intensive interests due to their potential applications in optoelectric devices, xerographic devices devices and sensors. Generally, photoconductive polymers are either conjugated polymers or polymers containing chromophore in their main chain. However, disadvantage of these systems is hard to optimize the intermolecular assembly to achieve high photoconductivity and photosensitive rate. Herein, we report synthesis and characterization of novel photoresponsive poly(spiropyran). Spiropyran is a well known organic dye exhibiting significant changes in optical properties as well as molecular conformations upon irradiation of light. Photoresponsive poly(spiropyran) shows increased conjugation length due to significant conformation changes with irradiation of light. The photoresponsive morphologies and optical properties of poly(spiropyran) have been characterized using SEM, TEM, PL and UV |
