Traceless release: A series of E and Z isomeric forms of arene RuII complexes bearing ligands derived from2,2′-azobispyridine is disclosed. The stability of the uncommon Z-configured complexes exhibiting 7-membered chelate ring involving two pyridines allows single crystal X-ray diffraction study to be reported here for the first time. Upon action of light, irreversible Z→E isomerization with rearrangement
无痕释放:公开了一系列带有源自 2,2'-偶氮二吡啶的配体的芳烃 Ru II配合物的E和Z异构形式。涉及两个吡啶的七元螯合环的罕见Z构型配合物的稳定性使得单晶 X 射线衍射研究首次在此报道。在光的作用下,发生不可逆的Z → E异构化和配位模式的重排,从而暴露出碱性氮原子。
