Full textAbstract
Abstract A series of trimethoxysilanes and silatranes coupled with distinct aromatic moieties (biphenyl, thiophene, pyrazine and pyridine) through amide linkage are reported. The synthetic approach involved the amidation of 3-aminopropyltrimethoxysilane (APTMS) with various carboxylic acids via acid chlorides ( 1a – 1g ) to generate amidopropylsilanes ( 2a – 2g ). Transesterification of the resultant silanes with triethanolamine and tris(isopropanolamine) yielded unsubstituted ( 3a – 3g ) and 3,7,10-trimethylsubstitued organosilatranes ( 4a – 4g ), respectively. The compounds were successfully characterized by various spectroscopic techniques [IR, NMR ( 1 H, 13 C) and Mass] and elemental analysis. The complete structure elucidation for compounds 3a , 3c ·H 2 O and 3f was carried out using single crystal X-ray diffraction analysis. The photophysical response was studied by UV–Vis absorption and fluorescence spectroscopy. These organosilatranes possess metal ion binding sites and can be put forth for advanced analytical applications.
