摘要:
以甲基邻苯二甲酸酐和丁二酸为起始原料, 经一系列反应同时得到了5, 5''-二甲基-2, 2''-联茚满-1, 1'', 3, 3''-四酮和3, 8-二甲基-6, 11-二羟基萘并萘-5, 12-二酮两种化合物.研究了它们的结构和性质, 结果表明, 这两种化合物互为同分异构体, 5, 5''-二甲基-2, 2''-联茚满-1, 1'', 3, 3''-四酮能产生稳定的自由基, 3, 8-二甲基-6, 11-二羟基萘并萘-5, 12-二酮既能产生稳定自由基又具荧光性.%5, 5'-dimethyl-2, 2'-biindanylidene-1, 1', 3, 3'-tetraone and 3, 8'-dimethyl-6, 11-dihydroxynaph-thacene-5, 12-dione were synthesized using 4-methylphthalic anhydride and butanedioic acid as the starting mate-rials. The structure and properties of the two compounds were investigated. The results show that, The two com-pounds are isomers, 5, 5'-dimethyl-2, 2'-biindanylidene-1, 1', 3, 3'-tetraone have paramagnetic. 3, 8'-dimethyl-6, 11-dihydroxynaphthacene-5, 12-dione can produce stable free radical and fluorescence.
