摘      要：Developing open-shell singlet(OS)diradicals with high luminescent properties and exceptional single-molecule magnetoluminescence(ML)performance is extremely ***,we propose a concept to enhance luminescent efficiency by adjusting the donor conjugation of OS diradicals,thereby achieving a highly luminescent diradical,DR1,with outstanding stability and making it a viable option for use in the emitting layer of organic light-emitting diodes(OLEDs).More importantly,the 0.5wt%-DR1 doped film demonstrates significant single-molecule magnetoluminescence(ML)properties.A giant ML value of 210%is achieved at a magnetic field of 7T,showing the great potential of DR1 in magneto-optoelectronic devices.
