Wide-range tunable circularly polarized luminescence in triphenylamine supramolecular polymers via charge-transfer complexation.

ABSTRACT: Circularly polarized luminescence materials with broad color tunability are highly valuable for applications in 3D display and photonic technologies. Here we show that incorporating intermolecular charge-transfer complexation into chiral supramolecular polymers is an efficient strategy to achieve this objective. Adjusting the charge-transfer strength between triphenylamine donors and naphthalenemonoimide acceptors enables tunable circularly polarized luminescence signals across the visible light spectrum. This includes blue-colored emission for the supramolecular donor polymers, as well as green, yellow, orange and red-colored emission for supramolecular donor-acceptor polymers. The donor-acceptor packing modes are further influenced by the presence or absence of acetylene linkages on the
