4CzIPN Usage And Synthesis

Description

1,2,3,5-Tetrakis(carbazol-9-yl)-4,6-dicyanobenzene (4CzIPN) is a thermally activated delayed fluorescence（TADF）material[1]. And it is a typical donor-acceptor fluorophore, in which carbazolyl is the electron donor and dicyanobenzene is the electron acceptor. Hence，4CzIPN has shown an excellent redox window, good chemical stability and broad applicability. The maximum emission of 4CzIPN in toluene at 507 nm，photoluminescence quantum yield（QY）=94.6%[2]. 4CzIPN can be used as a photocatalyst for organic transformation.

Uses

2,4,5,6-Tetra(9H-carbazol-9-yl)isophthalonitrile is an organic fluorescent dye.
