Abstract
The adenine-containing zinc(II) phthalocyanines 3, 4a, and 4b have been pre pared by standard O-alkylation of the tetrahydroxy analogue 1. These macroc ycles exhibit rather strong intermolecular interactions resulting in a poor solubility in organic solvents and unusual spectral properties that are hi ghly solvent-dependent. Self-assembly of the tetra-adenine phthalocyanine 3 and the thymine-containing 9,10-anthraquinone 6 through the Watson-Crick b ase-pairing interactions has also been demonstrated by fluorescence quenchi ng experiments.
