标 题:Expanded porphyrins and a method for synthesis thereof
发明人：OSUKA ATSUHIRO
权利人:JAPAN SCIENCE & TECH AGENCY
摘要:Novel meso-aryl substituted expanded porphyrins comprising of alternate arrangement of more than six of pyrrole units bridged by a methine group whose hydrogen is substituted with Ar-group; and their synthetic method. Ar-group is either a 2,6-substituted phenyl group which can possess a substituent at the other 3, 4, and 5 positions, or 9-anthryl group which can possess a substituent at the other positions of the anthracence, or a cyclohexyl group which can possess a substituent at the other positions of the cyclohexyl group. The substituents at the 2 and 6 positions mentioned above can be selected independently from halogen atom or lower alkyl group of carbon number 1 to 4, substituents at 3-5 positions, 9-anthryl group and cyclohexyl group can be selected independently from the group consisting of substituted or non-substituted alkyl of carbon number 5 or 6, substituted or non-substituted aryl group, besides above mentioned substituents at 2 and 6 positions. Each Ar-group can be different.
