Covalently scaffolded inter-π-system orientations in π-conjugated polymers and small molecule models

Abstract

Organic π-conjugated polymers have emerged as one of the most fascinating classes of materials as they have found utility in a host of plastic electronics technologies. The distance between u-systems and their relative orientation dictate energy/charge transfer, conductivity, and photophysical properties of these materials in bulk. This Feature Article discusses π-conjugated polymers and model compounds in which specific inter-rcsystem interactions are covalently enforced and the effect that the scaffolding has on optoelectronic properties.
