title: Di-pyrrolyl-pyrazoles: anion receptors in protonated form and efficient building blocks for organized structures.
abstract: Synthesis of di-pyrrolyl-substituted pyrazoles (dpp) and anion binding studies in protonated form are reported. Dpp show [2 + 2] binding of trifluoroacetate in the solid state to afford nanometer- and micrometer-scale architectures.
