Three tetraphenylethylene-based fluorescent single crystals (TPE-AA-1, 2, 3) were formed from different solvents, adopting three different self-assembly modes. One HOFs structure with characteristic porosity was obtained from acetonitrile/acetic acid as solvents. TPE-AA-3 showed the best detection performance for nitro explosives.
