英文摘要	Room temperature ionic liquids (RTILs) have been extensively studied with various applications owing to their non-volatility, excellent stability, good electrochemical properties and they can be easily manipulated by designing an appropriate structure and property. They differ from conventional solvents in that they have structural heterogeneity, which is one of the most essential natures of RTILs. In this work, the triplet excited state dynamics of meso-tetraphenylporphyrin (TPP) in the ionic liquid [Bmim][BF4] were studied, and it was observed that the triplet state lifetime of TPP increases remarkably from 2.95 to 184 mu s upon laser irradiation. These results of the dynamics of TPP triplet excited state are probably caused by the laser-induced microstructure changes of the ionic liquid, and the redistribution of oxygen molecules polarized by the external laser field and/or the ions in the heterogeneous microenvironment of the ionic liquid upon laser irradiation.
