摘要： 卟啉是一类重要的功能性小分子染料,近年来,在光化学治疗[1,2]、光电转换[3,4]、传感元件[5]、烯烃环氧化催化剂[6]和光敏化剂[7]等方面的研究与应用引起了人们的广泛注意.通过两亲卟啉分子衍生物,或带有负电荷的卟啉衍生物,特别是带磺酸基的卟啉分子与正离子聚电解质自组装,制备带有卟啉结构单元的LB膜和自组装膜已有很多报道[8～14].

Abstract: Tetra(4-diazoniumbenzene)porphyrin(TDBP) was synthesized via diazo-reaction of tetra-(4-aminobenzene)porphyrin(TABP). From the analysis results of MALDI-TOF mass spectroscopy and FTIR,it was confirmed that the synthesized porphyrin derivative mainly consists of tetra(4-diazoniumbenzene) porphyrin with trace tri- and di-substituted compounds. The self-assembly of TDBP with poly(styrene sulfonate)(PSS) was carried out and a novel TDBP/PSS multilayer ultrathin film on silicon substrate was obtained. The self-assembled film is very sensitive to heat and light,after heating or irradiation of UV light,the thin film becomes very stable towards polar solvents such as DMF. The coupling reaction of TDBP with phenol and the thermal stability of TDBP were also investigated preliminary.

Key words: Tetra(4-diazoniumbenzene)porphyrin, Poly(styrene sulfonate), Self-assemblly film
