Graphical Abstract

We propose an effective strategy for achieving circularly polarized organic ultralong room-temperature phosphorescence (CP-OURTP) with a high dissymmetry factor based on a bilayered soft helical superstructure doped with a light-driven molecular motor and room-temperature polymer layer. This enables the significant modulation of reflection across a wide spectral range and the dynamic controlling the dissymmetry factor of CP-OURTP from 1.38 to 0.60.

Abstract

Achieving circularly polarized organic ultralong room-temperature phosphorescence (CP-OURTP) with a high luminescent dissymmetry factor (glum) is crucial for diverse optoelectronic applications. In particular, dynamically controlling the dissymmetry factor of CP-OURTP can profoundly advance these applications, but it is still unprecedented. This study introduces an effective strategy to achieve photoirradiation-driven chirality regulation in a bilayered structure film, which consists of a layer of soft helical superstructure incorporated with a light-driven molecular motor and a layer of room-temperature phosphorescent (RTP) polymer. The prepared bilayered film exhibits CP-OURTP with an emission lifetime of 805 ms and a glum value up to 1.38. Remarkably, the glum value of the resulting CP-OURTP film can be reversibly controlled between 0.6 and 1.38 over 20 cycles by light irradiation, representing the first example of dynamically controlling the glum in CP-OURTP.
