of these metal complexes lies in the optoelectronics areas, such as light-emitting devices (LEDs)[7], chemosensors[8], and photovoltaic devices[9]. Among these complexes, cyclometalated platinum (II) complexes with a square- planar d8 electronic configuration, have displayed their potential applications in light-emitting devices[10-12]. Many cyclometalated homo- or hetero-leptic platinum (II......
