Abstract

The multiresponsive behavior of functionalized water-soluble conjugated polymers (CPs) is presented with potential applications for sensors. In this study, we investigated the aqueous solubility behavior of water-soluble CPs with high photoluminescence and with a particular focus on their pH and temperature responsiveness. For this purpose, two poly(phenylene vinylene)s (PPVs)-namely 2,5-substituted PPVs bearing both carboxylic acid and methoxyoligoethylene glycol units-were investigated, with different amount of carboxylic acid units. Changes in the pH and temperature of polymer solutions led to a response in the fluorescence intensity in a pH range from 3 to 10 and for temperatures ranging from 10 to 85 °C. Additionally, it is demonstrated that the polymer with the largest number of carboxylic acid groups displays upper critical solution temperature (UCST)-like thermoresponsive behavior in the presence of a divalent ion like Ca. The sensing capability of these water-soluble PPVs could be utilized to design smart materials with multiresponsive behavior in biomedicine and soft materials.

摘要

功能化水溶性共轭聚合物（CPs）的多重响应行为被展示出来，具有传感器的潜在应用。在本研究中，我们研究了具有高光致发光的水溶性CPs的水溶性行为，并特别关注它们的pH和温度响应性。为此，研究了两种聚对苯撑乙烯（PPVs），即带有羧酸和甲氧基低聚乙二醇单元的2,5-取代PPVs，羧酸单元的含量不同。聚合物溶液的pH和温度变化导致在pH范围为3至10以及温度范围为10至85°C时荧光强度产生响应。此外，还证明了羧酸基团数量最多的聚合物在二价离子如Ca存在下表现出类似上临界溶液温度（UCST）的热响应行为。这些水溶性PPVs的传感能力可用于设计在生物医学和软材料中具有多重响应行为的智能材料。
