摘要/Abstract

摘要： The β-carotene(β-Car) aggregate was prepared by self-assembly in cetyltrimethylammonium bromide (CTAB) micelle. The ground state absorption measurement showed that the aggregate has J-type characteristics and resonance Raman spectra gave the intrinsic explanation of molecular interaction in aggregate. Upon excitation at the optical allowed S₂ state of aggregate, direct generation of triplet state via singlet fission(SF) mechanism was observed. Excitation dynamics was elucidated by fs-transient absorption spectroscopy and ns-flash photolysis, respectively. The triplet state life time of aggregate was found to be independent of the ambient oxygen molecules.
