    Abstract: The novel compounds, 2,2''-bis(3-pyridinols), will fluoresce in the visible spectrum when exposed to ultraviolet light. The particular color emitted is dependent upon the other substituents on the pyridine ring. Generally, the parent compound and its substituted derivatives fluoresce green, unless the substituents have aromatic or aliphatic unsaturation which is conjugated with the unsaturation of the pyridine ring. This shifts the fluorescence to longer wavelengths, so that it is possible to produce compounds which fluoresce in the yellow and red portions of the visible spectrum. The compounds are readily soluble in common organic solvents and are thermally stable. They can be incorporated in various polymers to impart their fluorescent properties to the polymers. They can be incorporated in lacquers to produce films or applied as coatings on the envelope of ultraviolet lamps to produce various colored lights when energized.

    Abstract: Aryloxy and arylthio compositions are prepared from the reaction of a nitro- or fluorobenzene containing a carboxy group or a cyano group directly attached to the benzene nucleus with an alkali-metal salt of monovalent or divalent aromatic radicals in the presence of a dipolar aprotic solvent. The invention also embraces novel difunctional compounds prepared in accordance with the above-described process.

    Abstract: The subject compounds fluoresce in the visible and near-infrared regions of the spectrum when exposed to ultraviolet light. The particular color emitted (from blue to near-infrared) is dependent upon whether the hydrogen of the hydroxyl groups is present or has been replaced with various substituents, and upon the other hetero-atom in the benzazole ring. The compounds are photochemically and thermally stable and can be dissolved in organic solvents. They can be incorporated in various polymers to impart their fluorescent properties to the polymers which can be used to produce films, molded objects, or applied as coatings on the envelopes of ultraviolet lamps to produce various colored lights when energized.
