Abstract
We investigate the optical properties and intermolecular coupling of p ara-hexaphenyl polycrystalline films by site-selective spectroscopy, t ime-resolved photoluminescence and photoinduced absorption measurement s. Our results point to (i) a short-range orientational and energetic disorder and (ii) the molecular character of the light emission, with no evidence of intermolecular excited states.
