摘要：

A new colorimetric fluorescent receptor for H2PO4- is reported in this communication. The receptor can detect dihydrogen phosphates optically by developing a color change from yellow to green. Acute spectral responses to H2PO4- in HEPES buffer (DMSO-HEPES 1 : 9) have been observed. The selectivity zone in terms of pH of the receptor for H2PO4- is attributed to the fitness in the acidity (pK(a)) of receptor with H2PO4-. Hydrogen bonding plays the key role here which is confirmed by H-1 NMR titration. The receptor also has good potential for bio-imaging. The mode of interaction has also been established by ab initio calculation.
