Abstract: Quinhydrone is a 1:1 charge transfer complex of hydroquinone and p-benzoquinone having intermolecular hydrogen bonding. The effects of charge transfer on the photonconductivity of quinhydrone have been studied. The charge transfer complexes (CTCs) of quinhydrone with organic donors like 2, 2'-bis(quinoline), benzidine, DPPD, 2,2'-bipyridyl, TMPD and pyrene were prepared and studied using infrared spectroscopy. Strong envelopes are formed in the spectrum below 1800 cm-1. It interacts most with 2,2'-bis(quinoline) and least with pyrene. Other cases are intermediates. There is either free-carrier absorption or band-to-band transition above the gap region of the complexes and photoconducting gap is at lower frequency than Peierls gap.
