2-(2-(2-Pyrrolyl)ethenyl)phenanthroline exhibited trans-to-cis one-way isomerization on photoirradiation. Furthermore, the cis-isomer underwent intramolecular hydrogen atom transfer in the excited singlet state. The cis-to-trans isomerization took place efficiently on addition of a metal ion.
2-(2-(2-吡咯基)乙烯基)菲咯啉表现出反式-到-顺式上的光照射单向异构化。此外,顺式异构体以激发单线态进行分子内氢原子转移。该顺至-反式异构化发生在有效地加入金属离子。
