| 摘 要： | The aggregation of meso-tetrakis(4-hydroxyphenyl)porphyrin (H2THPP) in dimethylformamide (DMF)-water solution and in DMF-chloroform solution was studied by UV-vis absorption spectroscopy. The red shift of Soret band indicates the formation of J-type aggregates of H2THPP in these two solutions. However, different shift extent of Sorer band, 12 nm in DMF-water solution and 32 nm in DMF-chloroform solution, implies structural difference between these two J-type aggregates. The hydrogen bond between hydroxyl group and N-H bonds in porphyrin ring is thought as the main cause to the formation of J-type aggregate in DMF-chloroform solution, whereas the π-Q interaction between two adjacent porphyrin cores is thought as the main cause of the formation of J-type aggregate in DMF-water solution
