Abstract:
Copper(I) complex employed in organic light-emitting electrochemical cells (OLECs) are reported. During the study we found that the electroluminescence (EL) spectra under forward voltage redshifted compared with the photoluminescence spectra of the film. Moreover, the EL spectra under reverse voltage also redshifted compared with the forward EL spectra. Based on the electric-field theory and the device mechanism of OLECs, we suggest that the spectra shift is ascribed to the polarization effect of molecular orbitals under high electric field in the device. The polarization and radiation models under electric field have been proposed.
