Research Abstract |
In this project, we aim to develop three subjects in which we have recently found interesting seeds: (1) Development of molecular magnets based on radical-substituted radical cations (2) development of strong interaction systems involving molecular spins, and (3) development of highly efficient energy conversion systems utilizing spin-selective formation of radical ion pairs. (1) We developed two new magnets based onradical-substituted radical cations. (2) Two neutral diradicals having large positive exchange interactions were developed. A new π-donor substituted by three radicals with a doublet ground state was prepared and reversibly oxidized to a diradical cation with a triplet ground state havinga l (3) A new triad system with a strong absorption in the visible region due to Pt-porphyrine was prepared. The photoexcitation of the Pt-porphyrine moiety produced the radical ion pair with 680 μs lifetime.
