Mechanofluorochromic Difluoroboron <i>β</i> ‐Diketonates Based Polymer Composites: Toward Multi‐Stimuli Responsive Mechanical Stress Probes

Developing mechano-responsive fluorescent polymers that exhibit distinct responses to distinct mechanical stresses requires a careful design of the fluorophore in order to tune its interactions with the polymer. A series of mechanofluorochromic (MFC…

On the road for more efficient biocompatible two-photon excitable fluorophores

Red to NIR absorption and emission wavelengths are key requirements for intravital bioimaging. One of the way to reach such excitation wavelengths is to use two-photon excitation. Unfortunately, there is still a lack of two-photon excitable…
