Abstract

Organic-inorganic nanohybrids have been synthesized by in-situ coating of self-assembled, nanotubular J-aggregates with helically wound silica ribbons. The J-aggregates retain their outstanding optical properties in the nanohybrids, but with higher mechanical stiffness, better processability, and an improved stability against photo-bleaching and chemical ambients.
