More Than Carbazole Derivative Activates Room Temperature Ultralong Organic Phosphorescence of Benzoindole Derivative

, 2021
Herein, we report four carbazole/1H-benzo[f]indole (Cz/Bd) derivatives with increasing Bd substitution (Bd number=0~3), which give a general mechanism for Bd-based ultralong organic phosphorescence.

Switching Singlet Exciton to Triplet for Efficient Pure Organic Room-Temperature Phosphorescence by Rational Molecular Design

, 2023
The design and regulation of phosphor are attractive but challenging due to the spin-forbidden intersystem crossing (ISC) process. Here, a new perspective on the enhancement of ISC was proposed and demonstrated. Different from current strategies, the ISC

Liquid crystalline copper(i) complexes with bright room temperature phosphorescence [PDF]

, 2020
Phosphorescence in the liquid crystal state with one of the highest quantum yield values, 42%, at room temperature is reported. This property is achieved with cyclic trinuclear copper(I) complexes prepared using 3,5-dimethyl-4-(trialkoxyphenyl)pyrazolate
