Formation of inclusion complex between benzidine diammonium dipicrate and β-cyclodextrin with stoichiometry 1:2 (guest-host) has been established by UV, 1H NMR, 13C NMR, IR spectra and powder X-ray diffractometry. 1H NMR studies are used to confirm the inclusion and to provide information on the geometry of dipicrate inside the cavity of β-cyclodextrin.

The solid CT complexes of three benzidine derivatives with nine tri- and dinitrobenzenes are prepared and investigated by elemental analysis, IR, electronic absorption and proton magnetic resonance spectroscopy.The results of microanalysis revealed that strong acceptors can form 1:1 and 1:2 complexes, while weak acceptors form only the 1:1 type (donor : acceptor).The spectral changes revealed that acidic acceptors form complexes with ? - ?* electronic interaction and proton transfer, while non acidic acceptors yield complexes having the ? - ?* transition.
