Název projektu anglicky
Singlet Fission: Redox and Photophysics of Captodative Biradicaloids
Anotace anglicky
Singlet fission is an often fast process in which a singlet excited chromophore and its ground state neighbor share energy to produce a pair of triplet excited species. Recent intense interest in singlet fission is motivated by its potential utility in solar cell applications. The phenomenon has not been used outside of the laboratory so far, because the compounds best known to undergo singlet fission efficiently (tetracenes, pentacenes) are air and light unstable. They are also too large for truly accurate computations. We propose to prepare and examine an entirely new class of small molecules that have been computationally predicted to be suitable for singlet fission. They are biradicaloids derived from diketopiperazines, amino acid derivatives stabilized by the captodative effect. Presently, we shall study their one-electron reduction and oxidation, which are fundamental both for mechanistic understanding and for practical application. If these properties are found to be suitable, it will be useful to study their photophysical properties later.
