设计合成新型咔唑取代的卟啉衍生物5,10,15,20-四（氮-烷基）咔唑卟啉及其稀土乙酰丙酮配合物（Ln=Gd,Tb,Dy）, 并通过紫外 可见光谱、 红外光谱、 核磁共振氢谱、 质谱及摩尔电导等方法对配合物进行表征， 研究其荧光性质. 实验结果表明: 室温下稀土金属卟啉配合物Q带KG*8]荧光的量子产率为0.007 79~0.158, 是由稀土金属离子性质及无辐射跃迁强度不同所致.

Synthesis and Fluorescence Properties of Meso tetra(N-alkyl)-carbazolylporphyrins and Their Lanthanide Acetylacetone Complexes

We designed and synthesized a novel carbazole substituted symmetrical porphyrin derivatives, 5,10,15,20 tetracarbazole porphyrins and their lanthanide acetylacetonate (Ln=Gd,Tb,Dy) complexes. We characterized the complexes by means of UV Vis spectra, IR spectra, 1H NMR spectra, MS and molar conductances, and studied their fluorescence properties. Experimental resultsshow that quantum yields of Q band fluorescence of rare earth metal porphyrin complexes are 0.007 79—0.158 at room temperature. This is due to the different property of the rare earth metal ions and difference in the intensity of the radiationless transition.
