Amphiphilic block copolymers can form polymer micelles for delivering hydrophobic fluorescent probes with aggregation‐induced emission properties, as presented by A. K.‐Y. Jen et al. on page 1413 . By itself, 1,1,2,3,4,5‐hexaphenylsilole (HPS) exhibits dramatically enhanced blue‐green fluorescent emission efficiencies when encapsulated within the hydrophobic core of a polymeric micelle. When HPS is co‐encapsulated with bis(4‐( N ‐(1‐naphthyl) phenylamino)‐phenyl)fumaronitrile, effective orange‐red fluorescence resonance energy transfer can be demonstrated within live RAW 264.7 cells.
