A pillar[5]arene noncovalent assembly boosts a full-color lanthanide supramolecular light switch.

ABSTRACT: A photo-responsive full-color lanthanide supramolecular switch was constructed from a synthetic 2,6-pyridine dicarboxylic acid (DPA)-modified pillar[5]arene (H) complexing with lanthanide ion (Ln³⁺ = Tb³⁺ and Eu³⁺) and dicationic diarylethene derivative (G₁) through a noncovalent supramolecular assembly. Benefiting from the strong complexation between DPA and Ln³⁺ with a 3 : 1 stoichiometric ratio, the supramolecular complex H/Ln³⁺ presented an emerging lanthanide emission in the aqueous and organic phase. Subsequently, a network supramolecular polymer was formed by H/Ln³⁺ further encapsulating dicationic G₁via the hydrophobic cavity of pillar[5]arene, which greatly contributed to the increased e
