研究了钴肟络合物晶体在光照射下分子手性的转变。 Co(III) 离子 d-d 跃迁的激发似乎比配体-金属电荷转移带的激发更有效地诱导手性变化，尽管后者在破坏引发手性转换的 Co-C 键方面更有效。手性变化随照射时间的变化显示出阶梯状行为，表明分子的手性转换与其最近的邻居相关。
Switching of molecular chirality under photo-irradiation was studied in a cobaloxime complex crystal. Excitation of the d-d transition of the Co(III) ion appeared to be much more effective in inducing the chirality change than excitation of the ligand-metal charge transfer band although the latter is more effective in breaking the Co-C bond that initiates the chirality switching. The chirality change versus irradiation time showed a steplike behavior suggesting that chirality switching of molecules occurred in correlation with their nearest neighbors.
