A simple ratiometric sensor (L1) for the cascade detection of Zn2+ and H2PO4− with high selectivity was reported based on the intermolecular charge transfer (ICT) mechanism.
A fluorescent sensor based on aggregation-induced emission for amines was prepared and its highly sensitive detection of hydrazine and application in living cell imaging were investigated in detail.
A novel fluorescent probe (XL-1) exhibited over 50-fold enhanced fluorescence in the presence of Hg2+ and no interference could be produced by other metal ions, anions and amino acids.
