Research Abstract

To investigate the mechanism of electroluminescence (EL) switching accompanying the spin transitionof [Fe(dpp)2](BF4)2 observed in an OLED consisting of a chlorophyll a-doped [Fe(dpp)2](BF4)2 film,several devices with dye molecules and electron blocking materials. It was determined that the ELswitching accompanying the spin transition was dominated by a change in the molecular orbitallevel concerning electron transport in [Fe(dpp)2](BF4)2.
