The control in surface hydrophobicity and water adhesion is extremely important for various applications in water harvesting, oil/water separation membrane, energy systems or biosensing, for example. Here, for the first time we show that the use of fluorescent monomers such as pyrene with various substituents differing by their hydrophobicity, size, or rigidity/flexibility can lead to surfaces with tunable hydrophobicity, water adhesion and fluorescence properties by a direct electropolymerization process. Seven original monomers with fluoroalkyl, alkyl, phenyl, adamantyl, and triethylene glycol substituents were synthesized and studied. The surface roughness is highly dependent on the substituent, and it seems that the fluorescence, although complex, correlates with the surface roughness. Superhydrophobic properties and highly oleophobic properties are obtained using fluoroalkyl chains due to the presence of nanostructured microparticles. In comparison to the structured absorption and emission bands of pyrene monomers, the pyrene polymers (oligomers) exhibit a broad structureless spectral shape both in absorption and in emission, which seems to be due to pyrene oligomerization and aggregation. This work is a first tentative attempt to combine superhydrophobic and fluorescent properties using an innovative strategy and opens new doors to explore in this domain.

具有可调节的疏水性，水粘附性和荧光特性的聚py的电沉积

例如，对于集水，油/水分离膜，能源系统或生物传感中的各种应用，表面疏水性和水附着力的控制极为重要。在这里，我们首次表明使用荧光单体（例如pyr），其疏水性，尺寸或刚度/柔韧性不同，具有各种取代基，可通过直接电聚合过程产生具有可调的疏水性，水附着力和荧光特性的表面。合成并研究了具有氟代烷基，烷基，苯基，金刚烷基和三甘醇取代基的七个原始单体。表面粗糙度高度依赖于取代基，并且似乎荧光尽管复杂，但与表面粗糙度相关。由于存在纳米结构的微粒，使用氟代烷基链可获得超疏水性和高度疏油性。与of单体的结构化吸收带和发射带相比，the聚合物（低聚物）在吸收和发射方面均显示出宽广的无结构光谱形状，这似乎是由于pyr的低聚和聚集。这项工作是尝试使用创新策略将超疏水和荧光特性相结合的初步尝试，并为该领域的探索打开了新的大门。polymers聚合物（低聚物）在吸收和发射方面均表现出宽广的无结构光谱形状，这似乎是由于pyr的低聚和聚集。这项工作是尝试使用创新策略将超疏水和荧光特性相结合的初步尝试，并为该领域的探索打开了新的大门。polymers聚合物（低聚物）在吸收和发射方面均表现出宽广的无结构光谱形状，这似乎是由于pyr的低聚和聚集。这项工作是尝试使用创新策略将超疏水和荧光特性相结合的初步尝试，并为该领域的探索打开了新的大门。
