Synthesis of a light-emitting copolymer with ionic conductivity

The phase separation between strong polar ionic conductive and apolar conjugated light emitting polymers in light emitting electrochemical cells (LECs) can be avoided with a novel luminescence copolymer EO NV containing a rigid conjugated light emitting segment di(dimethoxy styrene) naphthalene and a flexible ionic conductivity segment triethylene oxide on the skeleton chain synthesized using the Wittig reaction. FT IR, 1H NMR, UV Vis, GPC, etc. were used to characterize its molecular structure and to study its photoluminescence properties. The results showed that EO NV has good solubility in common organic solvents such as chloroform, tetrahydrofuran, benzene, pyridine, etc., and has film form processing properties. The maximum photoluminescence peaks of the copolymer in a chloroform and a solid film were 470 nm and 505 nm, respectively. EO NV is a functional blue green luminescent copolymer used for fabricating LECs devices by combining the control of the conjugation length and the processablility of the polymer with ionic conductivity.
