    • Novel metal porphyrin compositions useful as organic phosphors are provided. The novel compositions are prepared from commercially available porphyrin-containing starting materials. In one instance a novel palladium-containing porphyrin composition having a number average molecular weight of greater than 12,000 grams per mole was prepared from 5,10,15,20-tetrakis(3′,5′-di(hydroxy)phenyl)-21H-23H-porphyrin by reaction first with palladium(II) acetylacetonate, followed by reaction with 2-bromo-2-methylpropionyl bromide, and subsequent group transfer reaction of the alpha-bromo ester groups with 9,9-dioctyl-2-vinylfluorene in the presence of CuBr as a radical initiator. The product polymer exhibited a number average molecular weight of 12,884 grams per mole, a weight average molecular weight of 14,338 grams per mole, and a robust red phosphorescent emission. Porphyrin containing copoylmers comprising structural units derived from 9,9-dioctyl-2-vinylfluorene and 9-anthracenylmethyl methacrylate were prepared in a similar fashion.
    • 提供了可用作有机磷光体的新型金属卟啉组合物。 该新型组合物由市售的含卟啉原料制备。 在一种情况下,从5,10,15,20-四(3',5'-二(羟基)苯基)-21H(5')中制备数均分子量大于12,000克/摩尔的新颖的含钯卟啉组合物 -23H-卟啉通过首先与乙酰丙酮钯(II)反应,随后与2-溴-2-甲基丙酰溴反应,随后将α-溴酯基与9,9-二辛基-2-乙烯基芴的组转移反应 存在CuBr作为自由基引发剂。 产物聚合物的数均分子量为12,884克/摩尔,重均分子量为14,338克/摩尔,并具有坚固的红色磷光发射。 含有衍生自9,9-二辛基-2-乙烯基芴和9-蒽基甲基甲基丙烯酸酯的结构单元的含卟啉的共聚酰基酯以类似的方式制备。
