无溶剂微波法合成meso-苯基四苯并卟啉锌

采用无溶剂微波固相法,合成了meso-苯基四苯并卟啉锌(Zn-PnTBP,n=1,2,3,4),通过紫外-可见光谱表征了其结构。结果表明原料配比、研磨时间、微波辐射时间等对反应的主要产物和产率都有很大影响,最终确定了形成Zn-PnTBP的最佳条件:n(邻苯二甲酰亚铵)∶n(苯乙酸)∶n(乙酸锌)=1.0∶1.4∶0.8、研磨时间为5 min,在中等微波辐射下反应13 min,产率达到28%。

Electron transfer reaction of meso-phenyl-tetrabenzo-porphyrinato-zinc and dicyanobenzene at low temperature

The behavior of photon-gated spectral hole burning with meso-phenyl-tetrabenzoporphyrinato-zinc as electron donor and dicyanobenzene as electron acceptor dispersed in polymethylmethacrylate was investigated.The data of absorption spectrum of the photoproduct acquired through photon-gated hole burning process by high power density and long hole burning time at 20 K were given The mechanism of photomduced donor-acceptor electron transfer for the iarget system in photon-gated spectral hole burning was demonstrated.
