Spatially confined single-molecule folding achieves multicolor phosphorescence.

ABSTRACT: Possessing two ethylene units, guest triphenylamine derivatives are encapsulated by the cucurbit[8]uril (CB[8]) cavity to induce molecule folding to form a biaxial pseudorotaxane. Crucially, this structure facilitates the oriented polymerization of ethylene units exposed outside the cavity with acrylamide, producing a pure organic supramolecular polymer (p-TAPCB) that exhibits near-infrared (NIR) room-temperature phosphorescence (RTP) with a high quantum yield of 47.03% through the synergistic effect of macrocyclic confinement and polymerization. By adjusting the ratio of CB[8], the resulting copolymers show tunable phosphorescence color that changes depending on the excitation wavelength and concentration. Furthermore, phosphorescence resonance energy transfer (PRET) is employed in triphe
