Electron transfer, not energy transfer, was the major way to result in quenching of PPVs with cis-linkage and those downward curves presented the incomplete quenching from inaccessible fluorophore.

• 考虑到被包埋发色团的存在以及“作用范围”的影响，参考前人工作，我们引入了一个经过修正的Stern-Volmer方程，能很好的拟合顺式构型含量较多的PPV所呈现的线性下偏型Stern-Volmer曲线。
