Abstract

Cyanine dyes are triggered to form fluorescent H-aggregates in IL [Cnmim][BF4], whereas J-aggregates are observed to form in ILs with other anions as 2 wt% 1 M aqueous NaOH is added at room temperature; difference in hydrolytic properties of [BF4]− ILs over other ILs is hypothesized to be the reason.
