内容紹介 : The design of photoswitchable multifunctional molecules, materials and devices is an appealing field of research with a growing number of recent potential applications. In this regard, diarylethenes (DAE) are of particular interest since these photochromic molecules are excellent candidates for a wide variety of optical applications such as photomechanical conversion, photocontrol of DNA structure and living organisms but also optical data storage and super-resolution imaging. For these two latter areas, appending fluorescence properties to the DAE compounds would be highly beneficial thanks to the combination of the photoswitchable behavior of the photochromic reactions and the high sensitivity of fluorescence spectroscopy. In this lecture, three main categories of molecular systems based on DAE derivatives with fluorescent properties will be presented: (i) the DAE unit itself shows fluorescence properties, (ii) the DAE and the fluorescent units are associated non-covalently, and (iii) the DAE and the fluorophore are linked via covalent bonds. Structural characterizations, steady-state and time-resolved spectroscopy investigations, from the ensemble level down to the single nanoparticle level, will be developed to quantify the switching efficiency, demonstrate nonlinear photoswitchable fluorescent properties, and decipher the processes driven at the nanoscale (intra- and intermolecular energy transfer) leading to amplification effects when a large number of chromophoric species are involved.
