Self-cleaning MOF: realization of extreme water repellence in coordination driven self-assembled nanostructures.

ABSTRACT: Bio-inspired self-cleaning surfaces have found industrial applications in oil-water separation, stain resistant textiles, anti-biofouling paints in ships etc. Interestingly, self-cleaning metal-organic framework (MOF) materials having high water contact angles and corrosion resistance have not been realized so far. To address this issue, we have used the fundamentals of self-assembly to expose hydrophobic alkyl chains on a MOF surface. This decreases the surface free energy and hence increases hydrophobicity. Coordination directed self-assembly of dialkoxyoctadecyl-oligo-(p-phenyleneethynylene)dicarboxylate (OPE-C₁₈ ) with Zn^II in a DMF/H₂O mixture leads to a three dimensional supramolecular porous framework {Zn(OPE-C₁₈)·2H
