| description | Abstract
The temperature-dependent dual fluorescence from a single component of small organic molecules (SOMs) is very promising for the ratiometric fluorescence sensing of temperature. However, the SOM-based fluorophores typically only show one fluorescence band. It is thus very challenging to achieve dual fluorescence, let alone the dual fluorescence that is sensitive to temperature. Herein, in this short review, we briefly summarized the examples of SOM-based fluorophores exhibiting temperature-dependent dual fluorescence. Through representative examples, we mainly focus on the illustration of the intrinsic mechanisms of this unusual phenomenon, which may take place because of the presence of two local minimum conformations that are thermally equilibrated in the ground state, the presence of two local minimum conformations in the first excited state as the result of significant structural relaxation upon excitation, or the presence of thermal equilibrium between the first and second excited states. Hopefully, the discussions in this short review will provide some important guidelines for the further rational molecular design of such fluorophores. |
