摘要：

A film of a spin-crossover complex [Fe(dpp)(2)](BF4)(2) (dpp = 2,6-di(pyrazol-1-yl)pyridine) was embedded into the light-emitting layer of an organic electroluminescent (EL) device with chlorophyll a. While the EL spectrum was observed at 300K, the spectrum could not be observed at 200 K. The temperature dependence of the EL spectra shows the quenching of the emission below 260 K, which is the spin-transition temperature of [Fe(dpp)(2)](BF4)(2). This suggests that the EL quenching accompanied the spin transition.
