Suppression Effect and Coupled Two-Time Motion of the Photoisomerization in the Crosslinking Polymer System

가교 고분자 계에서 광이성질화의 억제효과와 두 시간상수의 동적 특성 연구

The photoisomerization of the crosslinked and uncrosslinked polymer-pair with azo linkages was studied by the photoinduced birefringence. The amount of photoinduced birefringence of crosslinked polymer system was much smaller than that of uncrosslinked polymer system, even when varying pumping laser power, so the photoisomerization of an azo chromophores could be controlled by crosslinking process.
