Inorganic polymers and use of inorganic polymers for detecting nitroaromatic compounds
View Patent ↗A method for detecting an analyze that may be present in ambient air, bound to a surface or as part of complex aqueous media that includes providing a metallole-containing polymer or copolymer, exposing the polymer or copolymer to a suspected analyze or a system suspected of including the analyze, and measuring a quenching of photoluminescence of the metallole-containing polymer or copolymer exposed to the system. Also included is a solid state inorganic-organic polymer sensor for detecting nitroaromatic compounds that includes a substrate and a thin film of a metallole-containing polymer or copolymer deposited on said substrate.
1. A method for detecting an analyte that may be present in ambient air, on a surface or as part of complex aqueous media comprising:
providing an inorganic-organic metallole-containing polymer or copolymer with a backbone including carbon atoms bonded to metalloid atoms;
exposing said polymer or copolymer to a suspected analyte or a system suspected of including the analyte; and
measuring a quenching of photoluminescence of said polymer or copolymer exposed to said system.
2. The method of claim 1 further comprising selecting the polymer or copolymer to be one of the group consisting of PDEBSi, PDEBGe, PDEBSF, and PDEBGF.
3. The method of claim 1 wherein the polymer or copolymer is cast as a thin film.
4. The method of claim 3 wherein the thin film is deposited on a solid surface.
5. The method of claim 1 wherein the polymer or copolymer is sprayed onto a solid surface having the analyte disposed thereon to form a thin film of the polymer or copolymer on the solid surface.
6. The method of claim 5 wherein the solid surface comprises one of glass, paper, metal, plastic, porcelain or wood.
7. The method of claim 1 wherein said step of exposing said polymer or copolymer comprises submerging the polymer or copolymer in an aqueous solvent.
8. The method of claim 1 wherein said step of exposing the polymer or copolymer comprises submerging the polymer or copolymer in an organic solvent.
9. The method of claim 1 wherein said step of measuring a quenching of photoluminescence includes illuminating the polymer or copolymer with light having a wavelength of between 250 nm and 420 nm and observing photoluminescence quenching.
10. The method of claim 1 wherein said step of measuring a quenching of photoluminescence includes subjecting said polymer or copolymer to fluorescence spectrometry.
11. The method of claim 1 wherein the metallole-containing polymer or copolymer is provided as an inorganic-organic polymer sensor that comprises a substrate and a thin film of the metallole-containing polymer or copolymer deposited on the substrate.
12. A method for detecting an analyte that may be present in ambient air, on a surface or as part of complex aqueous media comprising:
providing an inorganic-organic metallole-containing polymer or copolymer, said polymer or copolymer being a synthesis product of hydrosilation or hydrogermylation of an organic dialkene or dialkyne by a dihydrometallole;
exposing said polymer or copolymer to a suspected analyte or a system suspected of including the analyte; and
measuring a quenching of photoluminescence of said polymer or copolymer exposed to said system.
