2,3,5,6-tetrakis(carbazol-9-yl)-1,4-dicyanobenzene Usage And Synthesis

Application

2,3,5,6-Tetra(9-carbazolyl)-terephthalonitrile can be used as an organic synthesis intermediate and a pharmaceutical intermediate, and can be used in laboratory research and development processes as well as in chemical and pharmaceutical production processes.

Description

2,3,5,6-tetrakis(carbazol-9-yl)-1,4-dicyanobenzene, also known as 4CzTPN, is a thermally activated delayed fluorescence（TADF）material. Since 4CzTPN has higher Frster resonance energy transfer (FRET) rate and reduced intersystem crossing/reverse intersystem crossing (ISC/RISC) cycles, it can be used as sensitizing host to prepare TADF sensitized hyperfluorescence organic light-emitting diode. The device shows excellent performance.
