The chain length dependence involving a chiral memory effect of 2,6-pyridylene ethynylene oligomers 'meta-ethynylpyridines' was investigated. The meta-ethynylpyridine oligomers associated with octyl β-d- glucopyranoside form a helical complex giving induced CD; the induced chirality could be memorized with the help of Cu(OTf)2 as an additive. Contrary to our expectations, the study of the length dependence revealed that the 12-meric oligomer showed a more sustainable chiral memory effect than those observed in both of the shorter 6-meric and longer 18-meric oligomers.
