Rylene dye

Perylene dyes are useful for their intense visible light absorption, high stability, electron accepting ability, and unity quantum yields.

[1] Due to these properties, they are actively researched in academia for optoelectronic and photovoltaic devices, thermographic processes, energy-transfer cascades, light-emitting diodes, and near-infrared-absorbing systems.

Perylene diimide derivatives were developed as industrial dyes due to their excellent chemical, photo, thermal, and weather stability.

[1][3][4] Several perylene pigments have been developed for artist's paints : Perylenediimide derivatives have been incorporated as n-channel field-effect transistors due to their strong electron affinities.

In particular, OFETs using highly packed perylene diimide derivatives with electron withdrawing groups such were found to have good air stability.
