   Abstract:
   A new colorimetric fluorescent receptor for H(2)PO(4)(-) 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 H(2)PO(4)(-) in HEPES buffer (DMSO-HEPES 1:9) have been observed. The selectivity zone in terms of pH of the receptor for H(2)PO(4)(-) is attributed to the fitness in the acidity (pK(a)) of receptor with H(2)PO(4)(-). Hydrogen bonding plays the key role here which is confirmed by (1)H NMR titration. The receptor also has good potential for bio-imaging. The mode of interaction has also been established by ab initio calculation.
