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 chargetransfer 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.
