Modulation of excited state proton transfer

摘要: Abstract The mechanism of excited state proton transfer (ESPT) has been widely investigated in various fields, owing to its fundamental role many systems. ability regulate the ESPT process enabled range applications be greatly expanded, and corresponding investigative work become increasingly sophisticated. In particular, unmeasurable quantities at a molecular level are great interest. As modulation technology forms foundation ESPT, development is worthy further exploration discussion. this article, we summarize recent approaches regulation, including use solvent polarity, electric medium. We also consider mechanisms related applications, discuss debate over whether stepwise or concerted occurs systems double transfer. Finally, challenges research present some ideas that may guide future progress.
