Abstract

Nature is a source of inspiration for humankind and helps in technological advance. As a matter of fact, the reproduction of the photosynthesis, where natural chromophores absorb the incoming sunlight, is a long seeking challenge. To mimic such antenna systems new organic dyes are designed. However, single molecules show intrinsic limitations to absorb the whole electromagnetic spectrum, for light traveling, and to withstand prolonged irradiation regimes. To offset such shortcoming, multichromophoric dyes are an appealing alternative. In these complex molecular structures dissimilar dyes are covalently linked to promote energy transfer between them, which is the key pathway. Thus, multichromohores enable a broadband and efficient absorption. Therefore, multichromophoric dyes emerge as the next generation of ap-plied photoactive systems for artificial antennae in optic and photovoltaic devices. Herein, we detail the main structural and photophysical requirements to develop efficient and stable multichromophores. As a proof of concept, we showcase multichromophoric dyes based on rhodamine, perylene red and BODIPY and describe their photonic performance applied as lasers and sensors.
