• Photo-physical properties of substituted organotriethoxysilanes.
• Chalcones bearing terminal alkyne group (7a–7u) were synthesized.
• Organotriethoxysilanes has applications in material science and biology.
Organotriethoxysilanes (OTES) play an impressive role in the designing of organic–inorganic hybrid materials. The highly efficient copper catalysed ‘Click Silylation’ is followed for the functionalization of 3-azidopropyltriethoxysilane (AzPTES) with a series of acetylinic chalcones. Chalcones being ubiquitous subunits present in various natural products possess a wide variety of biological activities and are thus considered for the synthesis of new hybrid templates. Twenty one new chalcone holding triazole encapped OTES were synthesized in quantitative yields. All the synthesized compounds were well characterized by IR, 1H and 13C NMR spectroscopic techniques. The photo-physical properties of all the OTES were compared and the effect of different substitutions was explicated. These OTES can be put to amazing applications in the field of medicine and material chemistry.
Chalconyl blended triazole allied organotriethoxysilanes (8a–8u) were synthesized from acetylinic chalcones (7a–7u) by ‘Click Silylation’. The photo-physical properties of all the synthesized silanes were evaluated and the effect of different substitutions was studied.Figure optionsDownload as PowerPoint slide
