In this work, 5, 11-diethyl-6-formylindolo[3,2-b]carbazole (DEFICZ) was crystallized in a monoclinic crystal system with the space group of P121/n1. Its spectral properties and potential interaction with protein including BSA and HSA were also studied correspondingly. The crystal structure was theoretically investigated using the density functional tight-binding method. In order to address the regioselective associated with the synthesis of DEFICZ, the B3LYP density functional theory (DFT) calculation has been carried out to estimate the relative stability of different active intermediates. In addition, time-dependent density functional theory method was used to unveil the origin of the absorption spectra of DEFICZ as observed experimenta.

Two novel indolo[3,2-b]carbazole derivatives, 5,11-di(4′- dimesitylboronphenyl)indolo[3,2-b]carbazole (DDBICZ) and 2,8-dimesitylboron-5, 11-di(4′-dimesitylboronphenyl)indolo[3,2-b]carbazole (DDDBICZ), were synthesized by introducing two dimesitylboron groups and/or four dimesitylboron groups (as electron-acceptors) into the indolo[3,2-b]carbazole moiety (as an electron-donor). The structures of these two compounds were fully characterized by elemental analysis, mass spectrometry and proton nuclear magnetic resonance spectroscopy methods. Their thermal properties were studied by thermogravimetric analysis and differential scanning calorimetry. Their electrochemical and photophysical properties were studied by electrochemical methods, UV-vis absorption spectroscopy and fluorescence spectroscopy. The charge-transporting properties of DDBICZ and DDDBICZ were studied by fabricating single carrier devices using them as charge-transporting layers. The results reveal that DDBICZ and DDDBICZ have high thermal stability (the decomposition temperature of DDBICZ = 201 °C and the decomposition temperature of DDDBICZ = 210 °C) and good electrochemical and electron-transporting properties. Moreover, in order to examine the electroluminescent properties of DDBICZ and DDDBICZ, Device A and Device B were fabricated by using them as light-emitting layers, respectively. The turn-on voltage, maximum luminance and maximum luminance efficiency of Device A are 6.1 V, 5634 cd m-2 and 2.96 cd A -1, whereas those of Device B are 3.6 V, 1363 cd m-2 and 2.88 cd A-1.

Indolo[3,2-b]carbazole-based thin-film transistors with high mobility and stability

, p. 614 - 618 (2007/10/03)
Proper functionalization of indolo[3,2-b]carbazole led to a new class of high-performance organic semiconductors suitable for organic thin-film transistor (OTFT) applications. While 5,11-diaryl-substituted indolo[3,2-b]carbazoles without long alkyl side chains provided amorphous thin films upon vacuum deposition, those with sufficiently long alkyl side chains such as 5,11-bis(4-octylphenyl)indolo[3,2-b]carbazole self-organized readily into highly crystalline layered structures under similar conditions. OTFTs using channel semiconductors of this nature exhibited excellent field-effect properties, with mobility up to 0.12 cm2 V-1 s -1 and current on/off ratio to 107. As this class of organic semiconductors has relatively low HOMO levels and large band gaps, they also displayed good environmental stability even with prolonged exposure to amber light, an appealing characteristic for OTFT applications.
Application of phosphorous trichloride in attempted bis-indolisation of cyclohexanediones and dimedone

The efficacy of phosphorous trichloride as a cyclising agent in Fischer-type bis-indolisation has been tried on 1,2-, 1,3- and 1,4-cyclohexanediones and dimedone. In each case, besides the respective bis(phenylhydrazone), a novel product is formed. The in
