Exceptionally Strong Effect of Small Structural Variations in Functionalized 3,4-Phenylenedioxythiophenes on the Surface Nanostructure and Parahydrophobic Properties of Their Electropolymerized Films

We report the design and synthesis of a series of 3,4-phenylenedioxythiophenes substituted at the benzene ring with 2-naphthylmethyl-, 1-naphthylmethyl-, and 9-anthracenylmethyl-groups

Scholarcy highlights

  • Electropolymerization of electron-rich aromatics/heteroaromatics to form conducting polymers is an easy and powerful technique to form surfaces of different nanostructures and hydrophobicity/wettability
  • The Altmetric Attention Score is a quantitative measure of the attention that a research article has received online
  • Understanding the factors governing the growth of the polymer nanostructures and controlling the surface morphology are the big challenges for the surface and materials science
  • We report the design and synthesis of a series of 3,4-phenylenedioxythiophenes substituted at the benzene ring with 2-naphthylmethyl, 1-naphthylmethyl, and 9-anthracenylmethyl-groups
  • The importance of water for gas bubble formation during electropolymerization and creation of the surface nanostructures has been demonstrated and discussed. The formation of these different nanostructures is accompanied by different wettability of the surface, from hydrophilic to highly hydrophobic
  • The sticky, parahydrophobic surface formed from 1Na-PheDOT showed high adhesion to water, with no water droplets moving after inclination of the surface to 90°
