Despite
the intensive research in room-temperature phosphorescent
(RTP) polymers, the synthesis of RTP polymers with well-defined macromolecular
structures and multiple functions remains a challenge. Herein, reversible
deactivation radical polymerization was demonstrated to offer a gradient
copolymer (GCP) architecture with controlled heterogeneities, which
combines hard segment and flexible segment. The GCPs would self-assemble
into a multiphase nanostructure, featuring tunable stretchability,
excellent
RTP performance, and intrinsic healability without compromising light
emission under stretching. The mechanical performance is tunable on
demand with elongation at break ranging from 5.0% to 221.7% and Young’s
modulus ranging from 0.5 to 225.0 MPa.
