Abstract: A method of preventing photodegradation of dyes and pigments used in textiles and paints by surrounding photosensitive molecules with metal clusters that can absorb the damaging ultraviolet photons before they reach and damage the photosensitive molecules. A photosensitive dye or pigment is incorporated into a metal organic framework, which provides a scaffold to offer protection from ultraviolet degradation either by preferentially absorbing the ultraviolet light or by reflecting it before it reaches the dye. Isolating the dyes inside of the metal organic framework also sharpens the spectral features of the dye molecules.

Abstract: The present invention provides a method of chemically analyzing complex mixtures using spectroscopy and chromatography by collecting spectroscopy data at multiple points along a chromatography column to identify and quantify analytes in minutes. Also disclosed is the related system for chromatography and in-column spectroscopy for chemical mixtures and a larger microfluidic system incorporating the chromatography and in-column spectroscopy system.

Abstract: The present invention provides a method of making an adsorbent material for protection and sensing applications from gas and liquid phase media by grafting sorbent moieties onto a rigid scaffold. The grafting can be to an organic linker of a metal organic framework by post synthetic modification, to the metal nodes of the metal organic framework via ligand displacement, or by intercalating the sorbent moiety into the pores of the metal organic framework either during formation of the scaffold or by diffusion into the pores after the scaffold is formed.

Abstract: Presented herein is a new concept of uniformly spin coating a flat surface with a stationary phase and creating a gas chromatography column by pressing a grooved lid, with micro-stamped ridges, down onto the coated substrate. The lids are molded out of commercially available rigid materials including epoxies so that when pressed onto a flat surface it will create an air tight seal. The epoxy material is rendered inert by a thin layer of gold.
