Polyethylene imines (PEIs) having 4-butylazobenezene group through methylene spacer groups were prepared, and their thermal as well as photochemical properties was investigated. PEI104 having longer methylene spacer was found to form an out-of-plane structure by heating into an isotropic phase and following cooling. The photochemical control of the molecular orientation of PEI104 between in-plane and
制备了通过亚甲基间隔基团具有 4-丁基偶氮苯基团的聚乙烯亚胺 (PEI),并研究了它们的热和光化学性质。发现具有较长亚甲基间隔物的 PEI104 通过加热到各向同性相并随后冷却形成面外结构。PEI104 分子取向在面内和面外结构之间的光化学控制可以通过热和光化学过程的结合来实现。
