Dual-functional integration of direct photoinitiation and luminescence in an aggregation-induced emission (AIE) dye-monomer resin

Le résumé fourni par la source

The ability to shape materials into precise three-dimensional geometries is crucial for advanced light-emitting functional devices. While laser nanoprinting enables the fabrication of custom 3D nanostructures, its reliance on two-photon polymerization (TPP) typically demands photoinitiators. This requirement complicates the integration of luminescent units, as their compatibility with the photoinitiators must be carefully managed. Herein, we introduce an aggregation-induced emission (AIE)-dye resin, in which the AIE dye serves a dual role as photoinitiator and emissive unit, enabling direct printing of arbitrary 3D nanostructures. This approach bypasses the traditional compromise between high-resolution patterning and luminescence performance.
