Abstract 2, 3-Diaryl substituted maleimides as model compounds of conjugated maleimide polymers [poly (RMI-alt-Ar) and poly (RMI-co-Ar)] were synthesized from 2, 3-dibromo-N- substituted maleimide (DBrRMI)[R= cyclohexyl (DBrCHMI) and n-hexyl (DBrHMI)] and aryl boronic acid using palladium catalysts. To clarify structures of conjugated polymer containing maleimide units at the main chain, 13 C NMR spectra of 2-aryl or 2, 3-diaryl ...
