一种新型含卟啉的环金属化有机配体的设计、合成与性质

摘要

Efficent aqueous-phase Aldol condensation,Adler condensation,Michael addition,Vilsmeier and Knoevenagel reaction were successfully employed to synthesize a new donor-π-acceptor（D-π-A） type C∧N∧N structure of the cyclometaled organic ligand： trans-4-[2-（5,10,15,20-tetraphenylporphyrin-2-yl）-ethenyl]-N-{4-[（2-phenyl-6-pyridine）pyridium]tolyl}-pyridium bromine salt（abbreviated as TPPB）,the compound was characterized by 1H NMR,13C-NMR and ESI-MS.Linear optical,thermostability and electrochemical properties of the novel ligand were investigated.The results showed that the target molecule had good solubility and fluorescence properties which were instructive explorations for pursuing new luminescent materials.%采用Aldol、Adler缩合、Michael加成、Vils-meier和Knoevenagel等反应合成一种新型的D-π-A型的含C∧N∧N结构的环金属化有机配体：反式-4-[2-（5,10,15,20-四苯基卟啉基）乙烯基]-N-{4-[（2-苯基-6-吡啶基）吡啶]苯甲基}吡啶溴盐（简写为TPPB）。用核磁共振氢谱、碳谱和电喷雾质谱等手段对其结构进行了表征,初步研究了该化合物的紫外-可见光谱、荧光光谱、电化学和热稳定性。结果表明目标化合物有较好的溶解性和荧光性质,为寻找新的发光材料进行了有益的探索。
