The preparation of two liquid crystals composed of a redox-active tetraazanaphthacene (TANC) framework is reported. The materials form smectic A (SmA) thin-film liquid-crystalline (LC) phases over a wide temperature range. Cyclic voltammetry analysis revealed that LC TANCs behave as organic electron acceptors. The electron mobilities of the thin films were determined by time- of-flight (TOF) measurements, which are the order of 10-4cm 2V-1s-1 in the SmA LC phase. This value is two orders of magnitude larger than those of amorphous organic semiconductors. To the best of our knowledge, very few reports exist on the electron-transporting behaviors of LC N-heteroacene semiconductors.

An efficient and inexpensive sulfated polyborate catalyst was applied for the rapid synthesis of quinoxaline derivatives from various substituted o-phenylenediamines and 1,2-diketones/alpha-hydroxy ketones using sulfated polyborate is described. The catalyst has the advantage of Lewis as well as Bronsted acidity and recyclability without significant loss in catalytic activity. The key advantages of the present method are high yields, short reaction times, solvent-free condition, easy workup, and ability to tolerate a variety of functional groups, which give economical as well as ecological rewards.

Cyclic voltammetry and controlled-potential electrolysis have been employed to examine the electrochemical behavior of some mono- and dichlorinated pyrazines, quinoxalines, and pyridazines at carbon and mercury cathodes in either acetonitrile or dimethylformamide containing a tetraalkylammonium salt. Unsubstituted pyrazine and pyridazine each exhibit a single reduction wave, whereas unsubstituted quinoxaline shows three cathodic waves. For the chlorinated compounds, an additional wave is seen for the reduction of each carbon-chlorine bond. Depending on the potential of the cathode, bulk electrolyses of dichlorinated pyrazines or quinoxalines afford either the monochlorinated or fully dechlorinated product, whereas the monochlorinated analogues undergo reduction to the dechlorinated species. Electrolyses of chlorinated pyridazines give dark colored solutions, but the products (apparently polymeric) cannot be detected or identified by means of conventional GC, GC-MS, and HPLC techniques.

We have developed a novel fluorescent scaffold 4 which is a 9-nitro-2,3-dihydro-1H-pyrimido[1,2-a]quinoxalin-5-amine derivative from the reaction between di-tert-butyl but-2-ynedioate and a quinoxaline molecule containing a dimethyl amine side tail in high yield. The synthesis of scaffold 4 involves an sp3 C-N bond cleavage mechanism which is not very common. The scaffolds 4 is emissive in the visible range lambdaem ? (517-540) nm with large stokes shifts (5005-6378) cm-1 in ethanol. Laser confocal microscopy of the live HepG2 cells treated with compound 4f shows that it can be used for live cell imaging in nanomolar concentrations.
