Exciplex wave function

The exciplexes with A values >0.2 eV and dipole moments which are smaller than those of the CT exciplexes are formed as a result of interactions between the CT state X(A D+) and non-polar (locally) excited complex states such as 1(A D) and 1(AD ) leading to stabilization of the CT state and to lowering of the dipole moment [116]. The coefficients Ci or C2, and C3 and C4 in the wave function (41) can be of comparable magnitude for such exciplexes. The value of A = 0.3 eV follows for the exciplex formed by the TPOB acceptor [l,3,5-tris(4-fert-butylphenyl-l,3,4-oxadiazolyl)benzene] with the TCTA donor [4,4/,4//-tri(A -carbazolyl) triphenyla-mine] based on EDOX = 0.69eV and EAred = —2.1eV, and the...
