Mesoporous hybrid materials of (oligo)phenothiazines covalently grafted onto MCM-41 or SBA-15 silica have been readily prepared from (oligo)phenothiazinyl carbamates. The phenothiazine precursors show interesting electronic properties according to electronic spectroscopy and cyclic voltammetry. The resulting electronically active hybrid materials display fluorescence and can be oxidized to give stable
共价接枝到 MCM-41 或 SBA-15 二氧化硅上的(低聚)吩噻嗪的介孔杂化材料很容易从(低聚)吩噻嗪基氨基甲酸酯制备。根据电子光谱和循环伏安法,吩噻嗪前体显示出有趣的电子特性。所得的电子活性杂化材料显示出荧光,并且可以在轻度氧化时被氧化以产生稳定的自由基 - 阳离子物种。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
