    Notizen: ---Core-extended perylenetetracarboxylic bisimides were prepared by Diels-Alder reaction followed by reduction, or by nitration followed by cyclisation. Highly fluorescent dyes were obtained with absorption regions from the visible to the NIR. Applications for solar energy harvesting, and quantum counters were suggested.

    Thema: Chemie und Pharmazie
    Notizen: The synthesis and properties of perylene-bisimides 4 with one carboxylic acid anchor group are described. The properties of 4 are strongly influenced by the spacer between the carboxylic acid group and the imide moeity. Dyes with aliphatic (4d-4g) and aromatic (4a-4c) spacers have been prepared.

    Pyrrolo- and Thiophenoperylenedicarboximides - Highly Fluorescent Heterocycles (1996)
    Weinheim : Wiley-Blackwell
    Liebigs Annalen 1996 (1996), S. 1587-1591 
    Details
    ISSN: 0947-3440
    Schlagwort(e): Perylenes ; Heterocycles ; Fluorescent dyes ; Fluorescent labelling ; Chemistry ; Organic Chemistry
    Quelle: Wiley InterScience Backfile Collection 1832-2000
    Thema: Chemie und Pharmazie
    Notizen: 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.

    Thema: Chemie und Pharmazie
    Notizen: Perylene-3,4-dicarboximides 2 are obtained by a decarboxylizing condensation of moderately sterically hindered primary amines with perylene-3,4,9,10-tetracarboxylic 3,4:9,10-bisanhydride (3) in the presence of water. Perylene-3,4-dicarboxylic anhydride (4) is prepared by hydrolysis of the imides with KOH in tert-butyl alcohol. The anhydride may be condensed with any primary amine to the corresponding imide. The imides are highly fluorescent and very photostable dyes.

    Notizen: Perylene-3,4-dicarboxylic anhydride (3) is prepared from technical grade perylene-3,4:9,10-tetracarboxylic anhydride (1) in 25% yield by a partial decarboxylation reaction using noncondensing amines. Perylene-3-carboxylic acid (4) and perylene-3,4-dicarboxylic imide (5) are prepared in the same way in yields of 24% and 76%, respectively, by a variation of the reaction conditions.

    Thema: Chemie und Pharmazie
    Notizen: The synthesis of a bifluorophoric perylene dye (4a) is described, in which the two chromophores are linked by a chiral binaphthyl unit. A strong exciton coupling of the two chromophores, a bathochromically shifted fluorescence and strong CD effects are observed. The structure of 4 is compared to the photosynthesis reaction center.

    Notizen: 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.
