Synthesis and property of new functionalized porphyrins

研究了以硝基烯烃为起始原料合成吡咯和卟啉的一般方法，得到了以下结果：(1)十二硫基卟啉(DTP)的合成这种卟啉具有一些特殊的性质，它比通常的四芳基卟啉更容易被氧化，并且在较低的能量下吸收光。Fe-DTP是一种高效的烯烃环氧化催化剂。(2)带有给体和受体的卟啉的合成：带有苯甲酰基和硝基的卟啉有加重的趋势(如S，这类卟啉的ESR谱显示出强烈的三联体，表明它们是聚集的)。铜-铜的距离估计为4A。(3)合成了四个糖基取代的卟啉类化合物，它们易溶于水，具有高效的光敏活性。(4)以酯、氰基、硝基为原料制备卟啉。合成了一种新的含吸电子基团的卟啉。从而为控制卟啉的性质开辟新的途径。

General synthesis of pyrroles and porphyrins starting from nitroalkenes has been studied and the following results have been obtained.(1)Synthesis of dodecathienylporphyrins(DTP) ; This porphyrins show several unusual properties ; it is more easily oxidized and absorbs light at lower energies than the usual tetraarylporphyrins. FE-DTP is an efficient catalyst for epoxidation of alkenes. (2)Synthesis of Porphyrins with donor and acceptor : Porphyrins with anisyl and nitro grouptend to aggragation(S, for example, the ESR spectra of such porphyrins show the strong triplet which indicate the aggregation of porphyrins. The distance of Cu-Cu is estimated to be 4A. (3)Porphyrins substituted with four sugar moieties are prepared, which are freely soluble in water and show the efficient photosensitizing activity. (4)Preparation of porphyrins with ester, cyano, nitro. A new porphyrin with electron withdrawing groups has been prepared. Thus, we could develop the new way to control the property of porphyrins.
