Abstract:

We used density functional theory(DFT) with the MPW3PBE functional to optimize the firefly oxyluciferin and derivatives. Based on the optimized molecular structures, the ionization potentials(IP), electron affinities(EA), hole extraction potentials(HEP), electron extraction potentials(EEP), as well as hole and electron reorganization energy(λ) were calculated to investigate the hole and charge transport properties. We used the time dependent density functional theory(TD-DFT)/TD MPW3PBE/6-31+G(d) method to calculate the electronic absorption spectra, the lowest excited singlet state(S1) and the fluorescence spectra of firefly oxyluciferin and derivatives. These theoretical calculations indicated that oxyluciferin and derivations could be used as charge-transport and light emitting materials simultaneously.

Key words: Firefly oxyluciferin, Density functional theory, Electronic transfer, Reorganization energy, Emission spectrum
