A solvatochromic dye monomer with an allyl group (ASCD) was polymerized together with methyl methacrylate (MMA) or styrene (St) to obtain hydrophobic fluorescent polymers. The wettability of the polymers to alcohols was examined by monitoring the fluorescence (FL) changes over time. On the one hand, when the ASCD-incorporated poly MMA (PMMA) film was exposed to liquid alcohols, a remarkable red-shift occurred instantly in the FL emission spectra for light alcohols such as methanol, ethanol, and propanol whereas for heavier alcohols, a blue-shift occurred first and subsequently a red-shift occurred gradually. On the other hand, the ASCD-incorporated poly St (PSt) film exhibited less significant FL change upon contact with the light alcohols owing to the relatively higher hydrophobicity. In contrast to the case of alcohols, the polymer films exhibited no FL response to water even after prolonged exposure. Particularly, the ASCD-incorporated PSt film showed a reversible and reproducible FL change during the repeated methanol and water contact cycle, indicating a high potential for use as a sensor to discriminate between light alcohol and water. Moreover, when the ASCD-incorporated PMMA was ground mechanically and added to the alcohols, the nanoparticle powder was dispersed very well in the alcohols. When the colloidal solution was deposited onto a paper as an ink, high-resolution FL images were obtained on the surface of the paper.

将具有烯丙基的溶剂变色染料单体（ASCD）与甲基丙烯酸甲酯（MMA）或苯乙烯（St）一起聚合以获得疏水性荧光聚合物。通过监测荧光（FL）随时间的变化来检查聚合物对醇的润湿性。一方面，当掺有ASCD的聚MMA（PMMA）薄膜暴露于液体醇时，对于轻质醇（如甲醇，乙醇和丙醇），FL发射光谱中会立即发生明显的红移，而对于重质醇，首先发生蓝移，然后逐渐发生红移。另一方面，由于相对较高的疏水性，与ASCD结合的聚St（PSt）膜在与轻质醇接触时表现出较少的显着FL变化。与酒精相比，即使长时间暴露，聚合物薄膜也没有表现出对水的FL响应。特别地，在重复的甲醇和水接触循环过程中，结合有ASCD的PSt膜显示出可逆和可再现的FL变化，表明用作区分轻质醇和水的传感器的潜力很大。此外，当将掺有ASCD的PMMA机械研磨并添加到醇中时，纳米颗粒粉末很好地分散在醇中。当将胶体溶液作为墨水沉积到纸上时，在纸的表面上获得了高分辨率的FL图像。表明用作区分轻质酒精和水的传感器的潜力很大。此外，当将掺有ASCD的PMMA机械研磨并添加到醇中时，纳米颗粒粉末很好地分散在醇中。当将胶体溶液作为墨水沉积到纸上时，在纸的表面上获得了高分辨率的FL图像。表明用作区分轻质酒精和水的传感器的潜力很大。此外，当将掺有ASCD的PMMA机械研磨并添加到醇中时，纳米颗粒粉末很好地分散在醇中。当将胶体溶液作为墨水沉积到纸上时，在纸的表面上获得了高分辨率的FL图像。
