absorption and emission spectra of single crystals of DPH and DPO; photophysics of coplanar structures of diphenylpolyenes; Stokes shift of diphenylpolyenes
The spectroscopy of the monoclinic and orthorhombic crystalline forms of all-trans-diphenylhexatriene (DPH) and all-trans-diphenyloctatetraene (DPO) shows absorption and emission bands without the widely known Stokes shift of polyene compounds discovered by Hausser et al. in 1953. It can be concluded from the study that the crystallization system, whether monoclinic or orthorhombic, does not significantly influence the photophysics of DPH and DPO in the crystal phase.
Spectroscopy of the monoclinic and orthorhombic crystalline forms of all-trans-diphenylhexatriene (DPH) and all-trans-diphenyloctatetraene (DPO) show absorption and emission bands that do not generate the widely known Stokes shift of the polyene compounds, discovered by Hausser et al. in 1953 and repeatedly studied over the last 60 years. It can be concluded from our study that the crystallization system, whether in a monoclinic or orthorhombic system, does not significantly influence the photophysics of DPH and DPO in the crystal phase.
