ortho-Azacrown-substituted (tetrafluorophenyl)imidazo[1,2-a]pyridine (2) in an acetonitrile solution emits 380 nm light in the presence of Li+ cation and emits 460 nm light in the presence of Zn2+, Mg2+ or H+ cation. In contrast, para-azacrown-substituted analogue (1) emits three different fluorescent lights responding to Li+, Zn2+ or H+ cation, respectively; 388 nm light to Li+ cation, 433 nm light to Zn2+ cation or 469 nm light to H+ cation.
