However, the spectral stability was increased, and the 0-1 transition and the full width at the half-maximum of photoluminescence spectra was decreased with the increase of the alkoxy length on phenylene. The nature (e.g. electron-donating and electron-withdrawing) of the substituted side groups on phenylene has obvious effect on the optical properties, QY and electrochemical properties of the polymers.

苯环上取代侧基的给吸电子性质变化对聚合物的光电性能具有全面的影响，改变取代侧基的给吸电子性质可调节芴苯共聚物的发光颜色和HOMO、LUMO能级以及HOMO-LUMO能隙等，因此，通过引入不同性质的侧基可以实现对此类聚合物光物理性能的调控。

The results demonstrated that both temporal and spectral cues are important for phoneme recognition in quiet and in noise.
