Polyazomethines with triphenylamine groups synthesized by Suzuki polycondensation reactions

Abstract

Two new linear, conjugated triphenylamine-based polyazomethines were synthesized by the Suzuki polycondensation of N,N′-bis[4-(4-bromophenyl) (phenyl)aminobenzylidene]-1,4-phenylendiamine with 2,5-thiophenediboronic acid and 9,9-dioctylfluorene-2,7-diboronic acid, respectively, using Pd(PPh 3) 4 as catalyst. The obtained structures were characterized by spectral methods ( 1H-NMR, FT-IR, UV-Vis and fluorescence), as well as by thermal analysis. © 2012 Koninklijke Brill NV, Leiden.
