Original Abstract

Multi-photon absorption (MPA) is the electronic excitation of a molecule induced by a simultaneous absorption of several photons, e.g. absorption of a pair of photons is referred as 2-photon absorption (2PA). The nature of MPA enable a large number of technological capabilities but two main areas are the most developing: 2-photon fabrication that uses 2-photon induced photopolymerization (2PP) and 2-photon microscopy (2PM). We focused on finding design rules that allow for construction highly efficient 2PA chromophores with large 2PA cross-sections based on intrinsically stable chromophore, the diketopyrrolopyrrole (DPP). This contribution focuses on study of two-photon absorption of several structural modifications of DPP and discusses the results of the application of general design rules for efficient 2PA dyes.
