Unveiling the Yellow Electroluminescence (EQE<sub>max</sub> = 5.4%) of an Unsymmetrical Perylene Diester Imide
An unsymmetrical perylene diester imide (PEIST), with flexible chains connected through imide and ester functionalities, was prepared through microwave-assisted synthesis. This compound displayed a remarkable fluorescence quantum yield of 87% and an exceptional performance in a host–guest OLED prepared by doping in CBP at 0.5 wt % concentration, providing an EQEmax of 5.4% complemented by a brightness of 4265 cd/m2.
