  aryl Grignard addition to 1-methyl-4-piperidone and direct aromatization of the resulting 4-aryl-4-piperidinols. The pyridines were N-alkylated to give sulfonate salts desired for their fluorescent properties. Study of selected compounds as laser dyes revealed several structures to be efficient dyes lasing in the 530-550 nm range. Two new diazaquaterphenyls were prepared and were quaternized. These salts

  A new class of proton transfer, benzazole, fluorescent compounds is composed of a 2-benzazolyl moiety covalently bonded to an aromatic fused ring heterocyclic moiety. The 2-benzazolyl moiety may be a 2-benzoxazolyl, 2-benzothiazolyl, or 2-benzimidazolyl. The aromatic fused ring heterocyclic moiety may be a 3-dibenzofuranyl or 3-dibenzothiophenyl each substituted at the 2 position with a proton donating group, or a 2-carbazolyl substituted at the 3 position with a proton donating group. The proton donating group may be hydroxy, sulfonamido, carbonamido, and the like, and preferably is hydroxy. The fluors are soluble in organic matrix materials such as solvents, monomers, resins, polymers, and the like. The UV-excited fluors emit short-lived fluorescence at .gtoreq.520 nm and may be used in the manufacture of fluorescent coatings, objects, scintillators, light sources and the like. The fluors are particularly useful for radiation-hard, solid scintillators for the detection and measurement of high energy particles and radiation and for UV filter materials.

  Dibenzofurans, a dibenzothiophene, and carbazoles, each substituted with a 2-benzoxazolyl group as well as an ortho-hydroxyl group, were synthesized to produce fluors with fluorescence due to excited-state intramolecular proton-transfer. The orientations for Friedel-Crafts acylation of 3-methoxydibenzothio-phene and of the analogous carbazole were determined. The fluors displayed absorption peaks in
