New linear π-conjugated polymers via Suzuki coupling of (1Z, 3Z)-1,4-dibromo-1,4-diaryl-buta-1,3-diene with aromatic diborates: Synthesis and photophysical properties

摘要: A series of new linear π-conjugated polymers have been synthesized via Suzuki coupling (1Z, 3Z)-1,4-dibromo-1,4-diaryl-buta-1,3-diene with aromatic diborates. The structures were characterized by NMR spectroscopy, IR spectroscopy and GPC. All them exhibit good thermal stability high decomposition temperature over 340 °C. It was found that the absorption emission can be adjusted through changing side group, partial twisted structure two groups at end carbon buta-1,3-diene unit hinder interchain interaction conjugated main chain improve photophysical properties in solid state. electrochemical electroluminescent primarily studied.
