    Description / Table of Contents: Enzyme-analogue Built Polymers, X. On the Synthesis of Monomers Capable for the Introduction of Amino Groups into Polymers in a Defined DistanceAs starting materials for the introduction of two amino groups into cross-linked polymers in a defined distance a number of bifunctional monomers were prepared. As templates dicarboxylic acids and especially dialdehydes with different distances of the functional groups were used. To these by amide bonds or azomethine bonds were bound each two polymerizable amines. The newly prepared dialdehydes 4,4′-methylenebis(biphenyl)-4′,4‴-dicarbaldehyde (13b), 2,2′-dinitro-4,4′-biphenyldicarbaldehyde (14), and 2,2′,2″-trinitro-p-terphenyl 4,4″-dicarbaldehyde (15) were particularly suited als templates. A total of 16 new bis(azomethines)(3,4,11,16-19) were prepared, with which it is possible to introduce two amino groups into a polymer with distances between 0.72 and 1.72 nm from each other.
    Notes: Als Ausgangssubstanzen zur Einführung von zwei Aminogruppen in vernetzte Polymere in definiertem Abstand wurden eine Reihe von bifunktionellen Monomeren hergestellt. Als Matrize dienten Dicarbonsäuren und vor allem Dialdehyde mit unterschiedlichem Abstand der funktionellen Gruppen, an die über Amid- bzw. Azomethinbindungen je zwei polymerisierbare Amine geknüpft wurden. Die neu hergestellten Dialdehyde 4,4″-Methylenbis(biphenyl)-4′,4‴-dicarbaldehyd (13b), 2,2′-Dinitro-4,4′-biphenyldicarbaldehyd (14) und 2,2′,2″-Trinitro-p-terphenyl-4,4″-dicarbaldehyd (15) waren besonders gut als Matrize geeignet. Insgesamt wurden 16 neue Bis(azomethine) (3, 4, 11, 16-19) dargestellt, mit denen sich zwei Aminogruppen in Abständen zwischen 0.72 und 1.72 nm voneinander in Polymere einführen lassen.
