Disordered Inverse Photonic Beads Assembled From Linear Block Copolymers.

ABSTRACT: Structurally colored colloids, or photonic pigments, offer a sustainable alternative to conventional dyes, yet existing systems are constrained by limited morphologies and complex synthesis. In particular, achieving angle-independent color typically relies on disordered inverse architectures formed from synthetically demanding bottlebrush block copolymers (BCPs), hindering scalability and functional diversity. Here, we report a conceptually distinct strategy to assemble three-dimensional inverse photonic glass microparticles using amphiphilic linear BCPs (poly(styrene-block-4-vinylpyridine), PS-b-P4VP) via an emulsion-templated process. By employing trans-1,2-dichloroethylene to promote interfacial water infiltration, nanoscale aqueous domains form within the organic phase and direct short
