For the reason that potential energy curve can not be overlapped the enantiotropy reaction of fulgides in the ground state was infeasible and fulgides were thermostable. 在第一单重激发态 ,有利于发生开环反应 ;
Potential energy curves of enantiotropy reactions in the ground state, the first singlet and the first triplet excited state were calculated by changing on-off bond-length of fulgides point by point. 计算结果表明 ,俘精酸酐分子在基态时 ,由于势能面不能重叠而不能发生变色反应 ;
