The carbazole-based PI shows excellent thermal stability with a high decomposition temperature up to 500 °C, refractive index of 1.74, and reasonable transparency of 85%. In addition, the PI exhibits characteristics similar to those of electrochromic materials such as violet-green emissions in the...

Carbazole22 '-bipyridine derivativesPhotophysical propertiesNLO propertiesComputation studiesThe development of donor-acceptor (D-A) architecture based organic chromophores with large two-photon absorption (2 PA) cross-sections are essential for myriad of applications, ranging from nonlinear microscopy to ...
Initially, a 4-((4-(9H-carbazol-9-yl)benzyl)oxy)-4-oxobut-2-enoic acid (CAV) was synthesized and esterified with a hyperbranched polyester polyol obtained from fourth generation (HBP) to synthesize carbazole-based hyperbranched polyester polyols (HBPCAV). The proportions employed of CAV were...
Carbazole-based donor−acceptor compounds 1,2-dicyano-trans-1,2-bis-4-(carbazolyl)phenylethylene (1) and 1,2-dicyano-trans-1,2-bis-4-(3,6-di-tert-butylcarbazolyl)phenylethylene (2) were synthesized. 1and 2show negative solvatochromic absorption behavior, but show both positive and negati...
A type of fluorescent–magnetic dual-function nanocomposite, Fe3O4@SiO2@P-2, was successfully obtained by Cu+-catalyzed click reaction between acetylene (CCH)-substituted carbazole-based conjugated polymer (P-2) and azide-terminated silica-coated magnetic iron oxide nanoparticles (Fe3O4@SiO2–N3)...
;SOLUTION: This carbazole-based polyamide comprises a structure of formula I (R<Sup>1</Sup> is an alkylene or a hetero atom; R<Sup>2</Sup> to R<Sup>5</Sup> are each H or an alkyl; (n) is 5-100). The carbazole-based polyamide, for example, is obtained by reacting (A) N-...
Synthesis of a new (E)-N1-((9-ethyl-9H-carbazol-3-yl)methylene)-5-nitrobenzene-1,2-diamine as a uorescent chemosensor for selective detection of Fe3 ion over a number of other metal ions is described. The method for the synthesis of the carbazole Schiff base was based on the ...
Monodisperse carbazole-based oligomers have been synthesized via C N bonds formation by the modified Ullmann reaction. The full characterization of their structure is presented. These derivatives are highly thermally stable amorphous compounds with glass transition temperatures of 167–171 °C and thermal...
Meanwhile, the probe is applied to the detection of Hg2+ in real water samples; and it is interesting that the DTCB-based test strip firstly reveals the strong fluorescence from solid-state 3-(4-formylphenyl)-9H-carbazole (FCB) with Hg2+ adding. The results show that the probe based on...
