Unusual near-white electroluminescence of light emitting diodes based on saddle-shaped porphyrins†
Abstract
In contrast to the red electroluminescence emission frequently observed in porphyrins based OLED devices, the present devices exhibit a nearly white emission with greenish yellow, yellowish green and blue green hues in the case of FeII(TCPPBr6) (TCPPBr6 = β-hexabromo-meso-tetrakis-(4-phenyl carboxyl) porphyrinato), ZnII(TPPBr6) and CoII(TPPBr6), respectively.
