The equilibrium constants of the aggregation of the metal porphyrin and the equilibrium constant of the π\|π coordination with phenothoroline have been measured by using UV\|Vis titration method. The results show that the equilibrium constants decrease in the order of K \-\{CuP\}> K \-\{NiP\}> K \-\{ZnP\}. The vitro anti\|tumor activities of the dibutyltin(Ⅳ) metal porphyrinate has some relation with the ability of aggregation and coordination with ligand of the metal porphyrin.展开更多

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. [WT5HZ]展开更多
