    Synthesis and characterization of novel ion sensor based on 2, 6-functionalized BODIPY structure
    (2012) Uyar, Taha Bilal
    Latest developments in chemistry of BODIPY make available synthesis of novel BODIPY based fluorescent chemosensors. Therefore, the design of novel chemosensors is attracting great attention in recent years. In this study, we functionalized 2 and 6 positions of BODIPY choromophore to understand that binding of different metal ions how affect the absorption and emission spectrums of BODIPY. We used three metal ions which are important in environment and biological systems and these are Hg (II), Zn (II) and Ca ions. Binding of these metal ions to azo crown ether is which attached BODIPY caused large changes in absorption and emission spectrums according to photoinduced electron transfer (PET) and internal charge transfer (ICT) mechanism.
