We describe a new class of near infrared (NIR) fluorescent dendrimeric quaterrylenediimide dyes with high photostability and hydrophilicity, functionality, as well as low cytotoxicity.

Broadly absorbing perylene dyes bearing three-triarylamine groups were synthesized via Sonogashira coupling. The triarylamine moieties allowed further installation of electron donating ability, to enable tuning of the oxidation potential and optical band gap. With introducing more electron-donating groups into the three-triarylamine moieties the device performance was improved. The trend can be rationalized by the distribution of the electron density in the HOMO of the perylene moiety as well as the light-harvesting property of the perylene dyes.

(Graph Presented) Fullerene C60-perylene-3,4-mono(dicarboximide) (C60-PMI) dyads 1-3 were synthesized in the search for new light-harvesting systems. The synthetic strategy to the PMI intermediate used a cross-coupling Suzuki reaction for the introduction of a formyl group in the ortho, meta, or para position. Subsequent 1,3-dipolar cycloaddition with C 60 led to the target C60-PMI dyad. Cyclic voltammetry showed that the first one-electron reduction process unambiguously occurs onto the C60 moiety and the following two-electron process corresponds to the concomitant second reduction of C60 and the first reduction of PMI. A quasi-quantitative quenching of fluorescence was shown in dyads 1-3, and an intramolecular energy transfer was suggested to occur from the PMI to the fullerene moiety. These C60-PMI dyads constitute good candidates for future photovoltaic applications with expected well-defined roles for both partners, i.e., PMI acting as a light-harvesting antenna and C60 playing the role of the acceptor in the photoactive layer.
