The derivatives of boradiazaindacene (BODIPY) are highly fluorescent dyes which
have quantum yields near 1.0. These dyes that have exceptional spectral and
photophysical stability as compared to other fluorescent groups are used for several
different applications.
The fluorescent sensor molecules for the detection of cations with PET
(photoinduced-electron transfer) mechanism in general have been obtained by the
differentiation of the BODIPY core. The extension of conjugation over the pyrrole
ring shifts the absorption and emission at longer wavelength. Moreover, it is seen
that red emission occurs from an ICT (intramolecular-charge transfer) state.

In this study, we designed and synthesized an unsymetrically substituted
BODIPY dye series, carrying a cation-sensitive phenylazacrown ether group
conjugated to the core, and investigated the ion sensing properties of these
compounds. Both aza-crown derivatives displayed selectivity towards Ca(II).
