Abstract: Provided is a novel donor-acceptor type compound which emits light even in a solid state. The present invention provides an organic optical material comprising a complex formed from (1) a conjugated molecule having (a) at least one electron donating site, (b) at least one electron accepting site, and (c) at least one conjugated site in the same molecule and (2) a compound having a proton donating property or an electron pair accepting property, the complex having a non-covalent interaction at the electron accepting site, wherein the complex is solid at ordinary temperature; and the organic optical material has a property of emitting light having a maximum fluorescence wavelength which causes a Stokes shift having a value corresponding to 5% or more of the value of a maximum absorption wavelength from the maximum absorption wavelength toward the long wavelength side.

Abstract: Provided are a donor-acceptor type compound having a novel structure and its use.An enamine compound represented by general formula (1) (in the formula: R1 represents an electron-withdrawing group; A represents a divalent aromatic hydrocarbon group which may contain a substituent, a divalent aromatic heterocyclic group which may contain a substituent or a divalent unsaturated aliphatic hydrocarbon group which may contain a substituent; R2 represents a hydrogen atom or a hydrocarbon group which may contain a substituent; R3 and R4 are the same or different from each other and represent an aromatic hydrocarbon group which may contain a substituent or an aromatic heterocyclic group which may contain a substituent, or R3 and R4 together form an optionally substituted bicyclic aromatic heterocyclic group containing two or more nitrogen atoms or a nitrogen atom and an oxygen atom or a sulfur atom, or a tricyclic aromatic heterocyclic group which may contain a substituent; and R2 and A, or R2 and R3 may together form a cyclic structure).
