Product Detail
1. Overview
The field of organic light-emitting diodes (OLEDs) is constantly evolving. Within the wide array of materials and compounds advancing this technology, mCPCN stands out as a promising candidate within the OLED stack due to its unique structure, a high-triplet-energy phosphorescent host material, featuring a benzene core and two carbazole units (one containing a cyano group.
mCPCN is mainly used as phosphorescent host material which could be used for hosting blue, green, red and white light emitting TADF-OLED devices.
