Abstract :
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.
