The crystal structure of a novel host 9,9′,10,10′-tetrahydro-9,10,9′,10′-biethenobianthracene -11,11′-bis-(diphenylphosphine oxide)-12,12′-diyl

Abstract The structure of a novel host 9,9′,10,10′-tetrahydro-9,10,9′,10′-biethenobianthracene-11,11′-bis-(diphenylphosphine oxide)-12,12′-diyl, named TBB briefly, has been determined by X-ray diffraction. The framework of TBB is highly twisted because of its bulky substituents. Two chloroform and three water molecules are included in each TBB molecule.
