New fluorescent sensors for aqueous copper ions were developed via screening of metal ligand libraries. Identified ionophores were linked to a dansyl fluorophore reporter, affording copper ion sensors based on fluorescence quenching. Simple chemical modification of identified ionophores generated sensors responsive to a broad range of copper ion concentrations (10 nM-35 μM).
New macrocyclic oligomers of isophthalic acid and trans-1,2-diaminocyclohexane are readily prepared and useful in the synthesis of new, sequence-selective receptors for peptides. Such receptors have a simple, two-armed structural motif and the peptide sequences they bind vary with the ring size of the macrocyclic arms.
