Abstract

The formation of a 1:2 inclusion complex between adamantyl tethered squaraine and β-cyclodextrin inhibited the aggregation of SQ in aqueous solution, enhancing the fluorescent emission of the near-infrared dye. The resulting SQ⊂β-CD complex serves as a sensitive fluorescent probe for imaging intracellular pH in living cells.
