    Description / Table of Contents: Zusammenfassung Ein neues Verfahren zur Bestimmung der Zusammensetzung binärer Flüssigkeitsgemische mit Hilfe solvatochromer Farbstoffe wird beschrieben. Die Analyse erfolgt durch einfache UV/VIS-Absorptionsmessung und ist unter Verwendung einer Zwei-Parameter-Gleichung ein exakter Schnelltest.
    Notes: Summary A new procedure for the determination of the composition of binary liquid mixtures by the use of solvatochromic dyes is described. The analysis, which consists of a simple UV/VIS absorption measurement in combination with a two parameter equation, provides an exact and rapid test.

    Notes: Perylene-3,4:9,10-tetracarboxylic acid 3,4-anhydride-9,10-imides are condensed with primary diamines to a number of new basic chromophores with amidine-imide structures. Lightfast dyes are obtained which exhibit a strong fluorescence in solution. The absorption and fluorescence spectra of the title compounds are bathochromically shifted compared to those of the perylene dyes.
