To tune their optical properties, a large variety of pyrrolopyrrole cyanines (PPCys) were synthesized with substitutedheteroaromatics such as quinoline, benzothiazole, and oxazole derivatives as terminal groups. Thus, a broad range of stable, highly fluorescing near-infrared (NIR) dyes with high absorptivities between 690 to 845 nm is accessible. The large number of newly synthesized compounds allows a detailed discussion of the correlation between molecular structure and the optical properties of the first electronic transition. Syntheses and optical properties of pyrrolopyrrole cyanines (PPCys) with different substituents at the terminal heteroaromatic moieties are described. The relationship between molecular structure and optical properties is discussed. By suitable substitution, the absorption and fluorescence maxima of the chromophore can be tuned in a range between 690 and 845 nm. Copyright

A process to make 6-phenyl-4H-s-triazolo[4,3-a][1,4]-benzodiazepines by converting 2-[3-(hydroxymethyl)-4H-1,2,4-triazol-4-yl]benzophenones to 2-[3-[(phthalimido or methanesulfonyl)methyl]-4H-1,2,4-triazol-4-yl]benzophenones and converting these compounds to the highly active 6-phenyl-4H-s-triazolo[4,3-a][1,4]benzodiazepines useful as tranquilizers and sedatives.
