摘要
以苯甲醛为基色团，4-醛-4′-(n -乙基- n -2-羟乙基氨基偶氮苯(BA)和3-异氰基丙基三乙基氧基硅烷(ICTES)为偶联反应合成了一种新型的烷氧基硅烷功能化推拉色团。将合成的烷氧基硅烷染料和四乙氧基硅烷(TEOS)进行水解缩合，得到了无机-有机杂化材料。该杂化材料具有良好的薄膜均匀性和光学清晰度。采用红外光谱、核磁共振、紫外可见光谱、热重分析和差示扫描量热法对分子的结构和物理性质进行了表征。对该材料进行了二次谐波产生和电光调制的研究。
Hybrid inorganic-organic films with Benzaldehyde-based chromophore for electro-optic device
A novel alkoxysilane-functionalized push-pull chromophore was synthesized through a coupling reaction between a benzaldehyde-based chromophore, 4-aldehyde-4'-(N-ethyl-N-2-hydroxyethyl aminoazobenzene (BA) and 3-isocyanatopropyltriethoxysilane (ICTES). Followed by a hydrolysis and condensation process of the resultant alkoxysilane dye and tetraethoxysilane (TEOS), hybrid inorganic-organic materials were obtained. The hybrid materials exhibited excellent film homogeneity and optical clarity. Molecular structural and physical properties were characterized by FTIR, NMR, UV-vis spectroscopy, thermogravimetric analysis, and differential scanning calorimetry. Second harmonic generation and electro-optic modulation studies were also conducted on this material.
