Design and synthesis of stable porous materials for sensing application

Abstract

Chapter 1- One triazine-based ether-linked luminescent porous covalent framework (PCF) has been synthesized. This compound was characterized with infra-red (IR) spectroscopy, thermogravimetric analysis (TGA), field emission scanning electron microscope (FE-SEM) and low-temperature gas adsorption measurements. Further, luminescence-based sensing of the toxic volatile organic compounds (VOCs) has been carried out with the aforementioned compound.

Chapter 2- Two spin crossover complexes {Fe-bpp(COOH), Fe(III)-Sal2tren} and one luminescent Coordination complex {Ru-bpp(COOH)} has been synthesized. These compounds were characterized by Infra-red spectroscopy, Powder-XRD, 1H-NMR spectroscopy. These complexes are encapsulated in a highly stable MOF (Zn-MFU 4l) with a high surface area. Further, these complex-loaded compounds are characterized by Infra-red spectroscopy, Solid-state UV-Visible spectroscopy, FE-SEM, Powder-XRD and Low-temperature gas adsorption studies. Magnetic measurement of the spin crossover complexes and the complex loaded compound has been carried out.
