title: Synthesis, structure, and hypochromism of (2,9)adeninophanes.
abstract: The title compounds 1a, b were synthesized via three steps in ca. 13% overall yield. X-ray crystallographic analysis of 1a revealed the non-stacked structure with dihedral angle of 122.0 degrees. Due to the non-parallel orientation, only small hypochromism was observed for 1a, b.
