    摘要: A chemical sensor consists of(a) a solid substrate,(b) a layer (D) which is applied to the substrate and contains one or more fluorescent compounds and(c) a layer (A) which is applied to the layer (D) and contains one or more coupling components (K) which, as a result of reacting with the analyte, give rise to one or more specific absorption bands, some or all of which overlap in the spectrum with the emission of the fluorescent compound of layer (D).

    摘要: A photoconductive layer is produced upon a substrate by coating the substrate with a solution in an organic solvent of a polyamic acid and of 2,4,7-trinitro-9-fluorenone (TNF) and/or 2,3,4,7-tetranitro-9-fluorenone and heating the coated substrate at a temperature not exceeding 150.degree. C. to form on the substrate a polyimide coating containing the said fluorenone compound as a photosensitizer.

    摘要: A photoconductive layer is produced upon a substrate by coating the substrate with a solution in an organic solvent of a polyamic acid and of 2,4,7-trinitro-9-fluorenone (TNF) and/or 2,4,5,7-tetranitro-9-fluorenone and heating the coated substrate at a temperature not exceeding 150.degree. C. to form on the substrate a polyimide coating containing the said fluorenone compound as a photosensitizer.
