Sensitivity Tuning of 9,10-Di(piperazinyl)anthracene Derivatives for Amphiphilic Assemblies by pH and Side-chain Modification with Monodisperse Oligo(ethylene glycol)s

Aiming to expand the range of applications of 9,10-di(piperazinyl)anthracene (AnP(2)) as fluorescent probes for aqueous environments, herein we investigated responsiveness of monodisperse-oligo(ethylene glycol)-modified AnP(2) to mi-celles and vesicles in buffer solutions. Both the length of the side chains and pH were found to significantly affect the sensitivity of AnP(2) for these aggregates.
