Abstract

An initiating system for the RAFT polymerisation of carbazole-containing styrene-type monomers in a wide range of molecular weights (3000–36 000 g/mol) has been developed. The proposed approach allowed to obtain carbazole-containing polymers with number average molecular weight up to 20 000 g/mol in a controlled fashion (degree of polydispersity <1.5). The relationship between the nature of donor substituents in carbazole, as well as the location of the carbazole moiety in the styrene and the activity of the corresponding monomer in radical polymerisation was studied. Experimental data gave good agreement with theoretical concepts and calculation models. The resulting polymers were characterised by high energy values of the highest occupied molecular orbital (up to –5.25 eV), which makes them promising materials for application in the LED industry.
