Abstract:Excitonic chromophore aggregates have wide-ranging applicability in fields such as imaging and energy harvesting, however their rational design requires adapting principles of self-assembly to the requirements of excited state coupling. Using the well-studied amphiphilic cyanine dye C8S3 as a template—known to assemble into tubular excitonic aggregates—we synthesize several redshifted variants and study their self-assembly and photophysics. The new pentamethine dyes retain their tubular self-assembly and demon… Show more
