General description

3,6-Di-tert-butylcarbazole is a carbazole based material with hole transporting characteristics. The 3,6-Di-tert-butyl component of the carbazole results in an increase in the glass transition temperature (Tg) of the compound. It can be used in combination with another carbazole to form novel electroluminescent materials.

Application

3,6-Di-tert-butylcarbazole is mainly used as a monomeric precursor in the syntheses of new carbazole based materials which consist of ethynylphenyl. These materials include 9-(4-bromophenyl)-3,6-di-tert-butylcarbazol and 2-(4-(2-(4-(3,6-di-tert-butyl-9H-carbazol-9-yl)phenyl)ethynyl)benzylidene)malononitrile (PBM) which can be further be used in organic light emitting diodes (OLEDs) and optical switching devices.

Bis(phenylsulfone) was developed as a strong electron acceptor of thermally activated delayed fluorescent emitters. The connection of two electron withdrawing phenylsulfone moieties through meta-position of phenyl produced the bis(phenylsulfone) acceptor and the strong electron acceptor strength of bis(phenylsulfone) enabled preparation
