基于吡啶基的二噻吩乙烯配位金属四苯基卟啉的设计合成及性能研究

摘要本文以2-甲基噻吩为原料，N-氯代丁二酰亚胺氯代，二酮加成及自缩合成环反应制得1,2-二(5-氯-2-甲基-3-噻吩基)-环戊烯，再通过与吡啶盐酸盐偶联生成1-(2-甲基-5-吡啶)噻吩-2-(2-甲基-5-氯)噻吩环戊烯和1,2-二(2-甲基-5-吡啶基)噻吩环戊烯，通过MS、1H-NMR验证了每步产物的结构，并用UV-Vis光谱探讨了两种光致变色分子的光致变色性能。以吡咯及苯甲醛为原料，丙酸为溶剂，并加入DMSO作为除水剂合成了四苯基卟啉，其结构经MS及1H- NMR进行表征，再将四苯基卟啉与金属进行配位生成金属四苯基卟啉，用MS对其进行结构表征，再用UV-Vis对其进行性能测试，验证其光致变色性能。然后将吡啶二噻吩环戊烯与金属配位四苯基卟啉配位生成金属四苯基卟啉配位吡啶二噻吩环戊烯化合物，利用MS对其进行结构表征，用UV-Vis对其进行性能测试，发现该化合物具有良好的光致变色性能，但难以实现荧光无损读取。33433

Title    Design, Synthesis and Properties of Bispyridylthenylethenes complex metallopophyrins
Abstract
The 2-Methylthiophene as raw materials,Chlorinate with N-Chlorosuccinimide，after diketone addition and self condensation cyclization reaction made 1,2-2(5-chloro-2-methyl-3-thienyl) - cyclopentene,then With pyridine hydrochloride coupling generated 1-(2-methyl-5-pyridine) thiophene-2-(2-methyl-5-chlorine) thiophene cyclopentene and 1,2-2(2-methyl-5-pyridyl) thiophene cyclopentene,verified by MS, 1H-NMR, the structure of each product,using UV - Vis spectra to discuss two kinds of photochromic properties of photochromic molecules.With pyrrole and benzaldehyde as raw material, propionic acid as solvent, and adding DMSO as dehydrating agent synthesized tetraphenylporphyrin and its structure confirmed by MS and 1H-NMR were characterized, then the tetraphenyl porphyrin and metal coordination to generate metal tetraphenyl porphyrin, MS was used for the structural characterization and then UV-Vis to test the performance to verify their photochromic properties.Then dithiophene cyclopentene coordinates metallporphyrin to generate etraphenyl porphyrin metal complexing dithiophene cyclopentene compounds，the structure of the structure was characterized by UV-Vis, and the performance of MS was tested.It is found that the compound has good photochromic properties
, but it is difficult to read the fluorescence without loss.
