    Notes: Synthesis of Nonsymmetrically Substituted Perylene Fluorescent DyesA general method for the preparation of perylene-3,4:9,10-tetracarboxdiimides 1 with two different substituents at the nitrogen atoms is described: The easily prepared symmetrical tetracarboxdiimides 1 (R1=R2) are transformed into carboxdiimide anhydrides 2 and condensed with primary amines to the corresponding tetracarboxdiimides 1 (R1 ≢ R2). Applications as fluorescent tracers in biochemistry and polymer chemistry are discussed.

    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.

    Pyrrolo- and Thiophenoperylenedicarboximides - Highly Fluorescent Heterocycles (1996)

    Notes: Pyrrolo- and thiophenoperylenedicarboximides 4 and 7 were prepared by reductive cyclization of 1-nitroperylenedicarboximides 3 and 5 with phosphorous acid esters and sulfur, respectively. The imides 4 and 7 are highly fluorescent and are easily monofunctionalized by nucleophilic substitution reactions which makes them useful for fluorescent labeling.
