Synthesis and Properties of Purinophanes: Relationship between the Magnitude of Hypochromism and Stacking Geometry of Purine Rings

Article abstract of DOI:10.1021/ja00215a032

Twelve purinophanes 1-12, in which two purine rings are fixed with different modes of stacking by two or three polymethylene chains, have been prepared by either stepwise introduction of the linking chains or quasi-dimerization of disubstituted purine der
