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.

α,ω-二苯基多烯 DPH 和 DPO 共面分子结构的电子态 S0 和 S1 的光物理学

的清一色的单斜和斜方晶系的结晶形式光谱-diphenylhexatriene(DPH)和清一色-diphenyloctatetraene(DPO)显示吸收和发射带不产生多烯化合物的公知的斯托克司频移,通过Hausser等人发现. 1953 年,并在过去 60 年中反复研究。从我们的研究可以得出结论,结晶体系,无论是单斜晶系还是斜方晶系,都不会显着影响晶相中 DPH 和 DPO 的光物理。
