摘　　要：设计合成了一系列新型的meso位N,N-二甲氨基苯基或N-苯基咔唑基单取代卟啉(5a^c)及其锌配合物(6a^c),用高分辨质谱、~1H NMR、紫外-可见光谱及X射线单晶衍射方法等对结构进行了表征;研究了卟啉化合物及其配合物的热稳定性及荧光性质。结果表明,这些卟啉化合物及其锌配合物在400~410 nm之间具有强的吸收且具有很好的热稳定性,荧光量子产率在0.05~0.09;另外还分析了meso位不同取代基对光谱性质的影响。A series of novel asymmetrical meso-mono-substituted porphyrin derivatives and their zinc complexes with N,N-dimethylphenylamine phenyl and N-phenyl-carbazole were synthesized. Their structures and photophysical properties were characterized by MS, 1H NMR, single Crystal X-ray diffraction analysis, thermogravimetric analysis （TGA）, UV-Vis absorption spectroscopy, and photoluminescence spectroscopy. The results showed that free base porphyrins （5a-c） and their zinc porphyrins （6a-c） exhibited a strong absorption in the range of 400- 450 nm with molar absorptivity of -10^5 L·mol-1 ·cm-1. Their emission were characterized in solution by large Stokes shifts （80-290 nm） and the fluorescence quantum yields ranged from 0.05 to 0.09. The compounds had also shown high thermal stability. In addition, the effect of the different subsfituent groups of the meso positions on the photophysical properties was studied. CCDC： 1450675, 5a; 1471067, 6a.
