Through iterative synthesis based on a highly selective intermediate of 4-isocyanate-4′-(3,3-dimethyl-2,4-dioxo-azetidine)-diphenylmethane, poly(urea/malonamide) dendrons bearing peripheral methyl methacrylate end groups with well-defined structures were realized. A coating solution was prepared by the combined use of 30–70 wt% UA dendron acting as dendritic diluents and dendritic UA copolymers acting as amphiphiles that can fabricate honeycomb-like surfaces via a breath figure self-assembly process using water droplets as templates. The resulting film can be cured under UV light to achieve a robust honeycomb-like structure with a hexagonal structure exhibiting solvent-resistant properties in ethanol. Consequently, this solvent-resistant porous array can act as a substrate for the detection of vanishingly low concentrations of analytes that are aqueous insoluble via surface-enhanced Raman scattering analysis. |
