| 摘要 |
The present invention relates to a nonlinear fluorescent molecule that generates a nonlinear fluorescence reaction by incidence of excitation light. This nonlinear fluorescence molecule includes donors (1) and (2), and an acceptor (3) that is coupled to the donors (1) and (2). As the donor (1) is excited by the incidence of the excitation light, electric charge moves from the donor (1) to the acceptor (3). Then, the donor (1) and the acceptor (3) form a charge separated state. In a state in which the charge separated state is maintained, the donor (2) fluoresces when transiting from an excited state to a ground state. |
