Synthesis and characterization of a novel carbazole cyclic oligomer and main-chain polymer

Synthesis and fluorescence properties of butadiyne-linked linear and cyclic carbazole oligomers

“…Several carbazole oligomers and polymers have been reported so far. [1][2][3][4][5][6][7][8][9][10][11] Since the bond angle between the 3-and 6-positions of carbazole is 90 , the oligomerization from these positions is expected to construct a stable cyclic tetramer. So, ethynyl-linked 1,6,8 and directly linked 5,11 cyclic carbazole tetramers have been synthesized.…”

Polycarbazoles: 25 Years of Progress

“…[64,65] Carbazolecontaining polymers, exhibiting both second order NLO and photoconductive properties have retained attention for their important role as photorefractive materials. [66][67][68][69] With this goal, Sasabe et al [70][71][72][73][74][75][76] have synthesised various linear and hyperbranched polymers, by Knoevenagel condensation, together with cyclic oligomers containing 3 and/or 6 acceptor-substituted carbazole chromophores linked by flexible spacers (Scheme 4). Materials could be efficiently poled by an electric field above T g and exhibit interesting second order NLO and photorefractive properties.…”

Synthesis and luminescent properties of Cu(II), Zn(II) polymeric complexes with electron- and hole-transporting groups

“…Carbazole and its many derivatives can be functionalized and thus they have been covalently incorporated into polymeric systems both in main-chain [6][7][8][9][10] as building blocks and in side-chains as pendant group [11][12][13][14]. Carbazole-containing polymers acting as hole-transportation materials and optical materials have been extensively studied, for example the first side-chain polymer PVK [15] and the main-chain polymer poly(3,6-N-2-ethylhexyl carbazolyl cyanotere-phthalidene) (PECCP) [16].…”
