out-of-plane molecular orientation on annealing and non-polarized visible light
irradiation. PEI8M in solid film exhibited photoresponsive properties upon
irradiation of UV and visible light. PEI8M film also exhibited reversible
molecular orientation from random state to out-of-plane and from out-of-plane
to random state on annealing, non-polarized UV and visible light irradiation.</span><span lang=\"EN-US\"><o:p></o:p></span>
