Synthesis of tetra (4-diazoniumbenzene)porphyrin and the self-assembled film with poly(styrene sulfonate)

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.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000222170400049&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701SCI(E)中文核心期刊要目总览(PKU)中国科技核心期刊(ISTIC)中国科学引文数据库(CSCD)0061180-11822
