Research Abstract |
Proton transfer (PT) is one of the most fundamental and important reactions in chemistry and biology. It has been considered that PT is simple reaction and the reaction mechanism can be understood along the one-dimensional reaction coordinate. However, recent development of experimental and molecular dynamics simulation techniques lead to detailed investigations on PT and show that PT couples strongly with both the other slow skeleton motion and fast electronic motion. In this project, we examined the reaction mechanism of proton transfer reaction in proton penetrate membranes. As the results, it has been clearly shown that strong hydrogen bond network is important for proton transfer rate and proposed a new material with high proton transfer rate by introducing a substituent.
