Alignment of supramolecular J-aggregates based on uracil-functionalized BODIPY dye for polarized photoluminescence.

A BODIPY dye functionalized with uracil-ethynyl groups at the 2,6-positions supramolecularly polymerized into J-aggregates directed by intermolecular H-bonds and featured intense absorption and resonant fluorescence. The alignment of J-aggregated chromophores in a thin film was achieved by a rubbing method and polarized photoluminescence with a dichroic ratio up to 14.3 was obtained. [ABSTRACT FROM AUTHOR]
