Abstract

Non-metallic phosphors with high thermal stability and low thermal quenching (TQ) are expected to achieve the development and application of environmentally friendly and low-cost efficient light-emitting diodes (LEDs). Herein, a novel non-metallic hydrogen-bonded organic framework (TCBPE-HOF) phosphor with aggregation-induced emission (AIE) characteristic is synthesized by the assembly of 1,1,2,2-tetra(4-carboxy biphenyl)ethylene (TCBPE) under a simple solvothermal method for efficient LEDs with low TQ. The TCBPE-HOF shows a rare example of a 4-fold interpenetrated network based on an 8-connected hex net. It can maintain 71% of its initial emission intensity after being heated to 150 °C, outperforming several commercial inorganic phosphors. The fabrication of cyan LED devices enables it to be a viable alternative to currently available commercial phosphors.
