Calix[4]arene sulfonate as a template for forming fluorescent thiazole orange H-aggregates

摘要

The unexpected interaction between thiazole orange (TO) and calix[4]arene sulfonate is reported herein. H-Aggregates of TO switching on their fluorescence in solution are observed. Surprisingly, fluorescence enhancement is not linked to host-guest inclusion, but rather to calix[4|arene sulfonate serving as a template for several TO molecules.
