POSS-Appended Diphenylalanine: Self-Cleaning, Pollution-Protective, and Fire-Retardant Hybrid Molecular Material.

ABSTRACT: Ordered self-assemblies of hybrid molecules have potential as protective umbrellas against environmental pollution and corrosion. This article describes the design and fabrication of a new self-cleaning hybrid molecular material containing polyhedral oligomeric silsesquioxane (POSS) and diphenylalanine as hydrophobic and pollution-protective coating. The colorless organic-inorganic hybrid materials, in which the diphenylalanine motif controls the self-assembly, exhibit unique water resistance property and enhance mechanical strength of paper 1.5-fold. The hybrid building blocks self-assemble in antiparallel sheet manner through noncovalent interactions to form a supramolecular layerlike surface with enhanced roughness. The hybrid material is soluble in organic solvents at room temperature
