Summary: | Organic solid luminescent materials bearing spectral tunability are receiving growing attention because of their enormous potential in the construction of stimulation-responsive smart materials. However, current methods, usually relying on polymer films or crystal aggregates, face challenges in fluorescence performance or crystallized controllability. In this work, we creatively report the use of surface-cross-linked micelles (SCMs), spatial confinement systems, to manipulate the multicolor fluorescence in the solid state by encapsulating a dihydrophenazine-based fluorophore (DPAC). DPAC can generate an intrinsic bent-to-planar configuration transformation with blue and orange-red fluorescence, respectively, and their intensity ratios strongly depend on different confined spaces provided by SCMs, thus enabling spectra-tunable fluorescence across blue to red regions. Interestingly, these self-assembly materials display the thermoresponsive peculiarities, which allow practical applications in intricate information encryption and elaborate logic circuit. Our strategy highlights the significance of the micelle-confined system that encloses the matched fluorophore as a tool to develop spectra-tunable and stimulus-responsive solid luminescent materials. |
