Rational design of COF–MOF composites for ratiometric fluorescence detection of phosphate

“…[19][20][21] Nowadays most lanthanide organic frameworkbased sensing methods of phosphate are achieved on the basis of intramolecular energy transfer by reacting with lanthanide ions or organic ligands. 22,23 However, the abovementioned lanthanide organic frameworks are single-emitting, and the sensing signal originating from fluorescent MOFs may easily be affected by probe concentration emission and excitation intensity. In contrast, ratiometric methods based on the ratio of dual fluorescence intensities can alleviate the abovementioned problems and results in excellent performance for sensing.…”
