Abstract

ABSTRACT In clustering‐triggered emission systems, molecules generally form clusters of various sizes, making it difficult to rationally design materials that emit a desired phosphorescence color. We achieved rational tuning of ultralong room‐temperature phosphorescence (URTP) color by hybridizing polystyrene sulfonic acid (PSS), which is a URTP material, with a silica network at varying mixing ratios. The results demonstrate that nanoscale confinement reduces the PSS domain size and thereby controls its phosphorescence color.
