The Stokes shift found by Hausser et al. in diphenylpolyenes, which increases by lengthening its polyene chain, has received in the last 80 years a series of explanations, which we believe are not satisfactory. In this current work, using of CS₂ as solvent for the fluorescence measurements of 1,6‐diphenylhexatriene (DPH) and 1,8‐diphenyloctatetraene (DPO) against temperature, it is concluded that the Stokes shift, shown by the diphenylpolyenes, is of structural origin and that it disappears from its photophysical behavior if it is possible that these compounds in their ground electronic state adopt a planar molecular structure, from which to initiate their photophysics.

二硫化碳溶剂，有助于阐明二苯多烯的斯托克斯位移

Hausser等人发现的斯托克斯位移。在过去的80年中，二苯多烯中通过延长其多烯链而增加的“二苯基多烯”已经得到了一系列解释，我们认为这是不令人满意的。在当前的工作中，使用CS ₂作为溶剂对温度进行1,6-二苯基己三烯（DPH）和1,8-二苯基辛酸酯（DPO）的荧光测量，得出的结论是，由二苯多烯表示的斯托克斯位移为如果这些化合物处于基态电子状态可能采用平面分子结构，从而从中引发光物理作用，则该化合物会从其光物理行为中消失。
