Description
Multi-component organic nanocrystals that are comprised of two or more supramolecular building blocks can be used to extend the design and assembly scope of solid molecular materials. Herein, we report the use of ultrasonication to prepare halogen-bonded stilbene-based nano-cocrystals that exhibit different photoemission properties, including one- and two-phonon emission and fluorescence lifetimes, relative to those of macrodimensional crystals. The structural transformation from nano-cocrystals into nanocrystals upon heating results in a luminescence red-shift from greenish blue to yellow. The temperature-dependent ratiometric luminescence may allow such nano-cocrystals to be used as fluorescent sensors and thermosensitive materials. Ultrasound as a pound: Halogen-bonding assembled nano-cocrystals that were prepared by using a sonochemical method showed sensitive temperature-dependent luminescence, owing to a transformation from nano-cocrystals into nanocrystals (see figure).
