A compound having chela shape, trans-9, 10-dihydro-9, 10-diphenyl phenanthrene-9, 10-diol(1), was synthesized. It could form the inclusion compounds with various small organic molecules such as DMF, DMSO, pyridine, piperidine, quinoline isoquinline. These inclusion compounds were confirmed by means of IR and powder XRD, and their host-guest molar ratio was determined by ^1H NMR. The results of four circle XRD for single crystal of the inclusion compound of the host molecule (1) with DMF shown that the host molecule (1) formed coordinatoclathrate with guest molecules.
