![عکس صفحه اول مقاله: Synthesis and properties of N-carbazole end-capped conjugated molecules Synthesis and properties of N-carbazole end-capped conjugated molecules](/preview/png/5230542.png)
A series of novel N-carbazole end-capped Ï-conjugated molecules were synthesized by a divergent approach with the use of bromination, Suzuki cross-coupling, and Ullmann reactions and their physical properties were investigated. In dilute solution, UV-vis absorption spectra displayed bathochromic shift with respect to their conjugated backbones, and photoluminescence spectra showed emission maxima in the blue region. Thermal analysis revealed that they are thermally stable semi-crystalline and amorphous materials. All molecules exhibited good electrochemical stability with high-lying HOMO energy levels and have potential applications as hole-transporting and light-emitting layers in organic light-emitting diodes or as host materials for electrophosphorescent applications.
A series of N-carbazole end-capped Ï-conjugated bisthiophenyl derivatives were synthesized and their optical, thermal, and electrochemical properties were investigated.
