【摘要】 采用溶胶-凝胶工艺,以正硅酸乙酯(TEOS)和乙烯基三乙氧基硅烷(VTES)为硅源,以VTES中的乙烯基(CH CH2)为有机改性剂,制备乙烯基改性二氧化硅凝胶玻璃,并在此过程中将四磺化酞菁镍(NiTSPc)掺杂其中制得复合凝胶玻璃。所得样品分别进行红外(IR)和紫外-可见(UV-Vis)吸收光谱的表征以测试其组成、结构和NiTSPc在复合体系中的存在状态。结果表明,VTES中的乙烯基被成功地引入SiO2网络并实现了对其改性;复合凝胶玻璃中NiTSPc的掺杂对基质的组成、结构未产生影响;NiTSPc在乙烯基改性后的凝胶玻璃基质中得到很好的分散,基本以单体形式存在。对所得结果进行了分析讨论。更多还原

【Abstract】 Nickel tetrasulfo-phthalocyanine（NiTSPc） was successfully doped into vinyltriethoxysilane（VTES）modified silicate gel glass by sol-gel technique,IR and UVVis spectral examination was carried out.The results show that vinyl has been introduced into SiO₂ network,and the structure of gel glass is therefore changed.The encapsulation of NiTSPc does not make any noteworthy changes in the composition and structure of gel glass matrix.NiTSPc molecules are well dispersed in the organic modified matrix,and the phenomenon of aggregation is greatly suppressed.更多还原
