The formation of J-aggregates in solutions of reverse micelles

Abstract

Features of BIC J-aggregate formation in AOT reverse micelles have been studied using steady-state absorption and luminescence spectroscopy and time-resolved luminescence spectroscopy. BIC J-aggregates reveal spherical structure with diameter ~ 20 nm and significant thermal stability. RM diameter decrease results in strong static disorder increase leading to J-aggregate band (J-band) widening and luminescence quenching. Due to high thermal stability BIC J-aggregates are embedded into RM as a whole at any temperatures of stock water solution. Decrease of stock water solution temperature leads to J-band narrowing and intensity increasing due to static disorder decreasing.
