Spectral and luminescent properties and electroluminescence of polyvinylcarbazole with 1,8-naphthalimide in the side chain.

A novel copolymer with moieties capable of charge transport and light emission on the basis of polyvinylcarbazole and 1,8-naphthalimide is synthesized. A bright and stable electroluminescence from single layered structure is observed. White light emission can be easily realized by tuning the content of naphthalimide moieties or a number of naphthalimide derivatives. Such approach can be considered as a common way to create single layered light-emitting devices with a stable white emission.
