Formation of higher-order structures of chiral poly(ethynylpyridine)s depending on size, temperature, and saccharide recognition
Amphiphilic 2,6-pyridylene ethynylene "meta-ethynylpyridine" polymers having chiral oligo(oxyethylene) side chains were developed as hosts for saccharide recognition. The polymers were prepared via a Sonogashira reaction and fractionated by gel permeation
