  Photoinduced Carbene Generation from Diazirine Modified Task Specific Phosphonium Salts To Prepare Robust Hydrophobic Coatings

  摘要：

  3-Aryl-3-(trifluormethyl)diazirine functionalized highly fluorinated phosphonium salts (HFPS) were synthesized, characterized, and utilized as photoinduced carbene precursors for covalent attachment of the HFPS onto cotton/paper to impart hydrophobicity to these surfaces. Irradiation of cotton and paper, as proof of concept substrates, treated with the diazirine-HFPS leads to robust hydrophobic cotton and paper surfaces with antiwetting properties, whereas the corresponding control samples absorb water readily. The contact angles of water were determined to be 139 degrees and 137 degrees for cotton and paper, respectively. In contrast, water placed on the untreated or the control samples (those treated with the diazirine-HFPSbut not irradiated) is simply absorbed into the surface. Additionaly, the chemically grafted hydrophobic coating showed high durability toward wash cycles and sonication in organic solvents. Because of the mode of activation to covalently tether the hydrophobic coating, it is amenable to photopatterning, which was demonstrated macroscopically.

  An array of highly fluorinated polymerizable phosphonium salts (HFPPS) were synthesized from PH3 and utilized in UV‐curable formulations. Inclusion of these salts at very low loading (0.1–1 wt %) into hexanediol diacrylate (HDDA) resulted in hydrophobic surfaces. The water repellency was achieved with short C4F9 fluorocarbon appendages in the monomer as opposed to the bioaccumulative C8F17 appended

  由PH 3合成了一系列高度氟化的可聚合phospho盐（HFPPS），并用于可紫外线固化的配方中。将这些盐以非常低的负载量（0.1–1 wt％）包含在己二醇二丙烯酸酯（HDDA）中会导致疏水性表面。与单体的生物累积性C 8 F 17相反，在单体中使用短的C 4 F 9碳氟化合物附肢即可达到拒水性附加的聚合物。还表征了这些新单体的物理性质。单体的分子结构对它们的物理性质以及在聚合物中赋予的疏水性程度都有明显的影响。利用双（三氟甲基磺酰基）酰亚胺阴离子的盐显示出与HDDA的优异相容性，而氯化物盐则不溶。飞行时间二次离子质谱（TOF-SIMS）证实了聚合物涂层表面上存在HFPPS。这首次证明了这些盐如何可用于功能化具有离子种类的UV固化膜的表面。©2013 Wiley Periodicals，Inc.
