研究目的
Investigating the modulation of excited-state proton transfer dynamics inside the nanocavity of microheterogeneous systems and its impact on F?rster energy transfer to riboflavin.
研究成果
The study demonstrates that the excited-state proton transfer process in TDMPP is significantly influenced by the microenvironment provided by surfactant assemblies. The physical characteristics of these assemblies, such as order, interfacial hydration, and surface charge, play crucial roles in modulating the proton transfer dynamics. Additionally, the study shows how these factors affect F?rster energy transfer from TDMPP to riboflavin in phospholipid membranes, highlighting the potential for multiparametric sensing applications.
