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 triphenylamine donors, resulting in ground- or excited-state charge transfer with varying luminescent lifetimes. Additionally, white-light circularly polarized luminescence is achieved by encapsulating blue- and orange-emitting species into surfactant-based micelles in a compartmentalized manner. Overall, manipulating charge-transfer complexation in supramolecular polymers provides an effective approach to wide-range tunable circularly polarized luminescence materials. Circularly polarized luminescence materials with broad color tunability are highly valuable for applications in 3D display and photonic technologies. Here, the authors incorporate intermolecular charge-transfer complexation into chiral supramolecular polymers to enable tunable circularly polarized luminescence signals across the visible light spectrum.
