The enantiopure helical ortho-oligo(phenylene)ethynylene ( o-OPE) core has been prepared by a new and efficient macrocyclization reaction. The combination of such o-OPE helical skeleton and a pyrene couple leads to two different CPL emission features in a single structure whose ratio linearly responds to silver(I) concentration.enPyrene-Containing ortho-Oligo(phenylene)ethynylene Foldamer as a Ratiometric Probe Based on Circularly Polarized Luminescence.research article29577727open access10.1021/acs.joc.8b001621520-6904PMC6145600https://pubs.acs.org/doi/pdf/10.1021/acs.joc.8b00162https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6145600/pdf
