Abstract:
Comparison of the anionic porphyrin′s RTP behaviors in different organized media was investigated. The results show that cationic surfactant CTAB or CPDB, nonionic Brij35 and BSA can improve RTP intensity of PdTCPP. When the concentration of CTAB is 2.0×10-5 mol/L, CPDB is 1.0×10-5 mol/L and Brij35 is 2.0×10-4 mol/L, the highest phosphorescence is respectively obtained. Whereas, anionic surfactant SDS can not influence the RTP intensity of PdTCPP. It can be concluded that, RTP intensity can not be enhanced, even if the microenvironment system is ordered and rigid. However, the interaction between phosphor and medium determines the increase in phosphorescence intensity.
