Single-Site Modifications and Their Effect on the Folding Stability of m-Phenylene Ethynylene OligomersClick to copy article linkArticle link copied!
Abstract
The folded structure of a m-phenylene ethynylene oligomer is tolerant to single-site modifications to both the backbone sequence and end groups. The helical structure is reinforced by multiple noncovalent interactions, allowing the oligomer sequence to be customized without a significant change in stability in most cases. The small changes that are observed are consistent with the expected behavior of π-stacked systems and demonstrate subtle control over folding through single-site modifications.
