Fluorescent receptor for dicarboxylates based on pyrrolecarboxamides
摘要:
Neutral ditopic and fluorescent receptor 1 based on two 2,5-pyrrolecarboxamide units shows a strong association with dicarboxylate anions such as glutarate and adipate through multiple hydrogen bonds. Fluorescence and H-1 NMR titrations display a 1: 1 stoichiometry for the complexes, with glutarate as the most strongly bound guest. Receptor 1 exhibits PET-induced fluorescence quenching upon recognition due to the presence of a dansyl group. The synthetic methodology described here might provide access to closely related receptors by the introduction of different fluorophores in the last step of the synthesis.
