Synthesis And Ion Sensing Properties Of Novel Boradiazaindacene Dyes

Zalim, Nalan 01 January 2003 (has links) (PDF)
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. iii 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).
