title: Synthesis, structure, and hypochromism of (2,9)(6,9)purinophane.
abstract: The title compound 1 was synthesized via 8 steps from phthalimide derivative 2. The molecular structure of 1 was determined by X-ray analysis and the relationship between the hypochromism and the stacking mode of two purine rings was discussed.
