However, emissive solids are not common because of the quenching resulting from the packing. With these considerations, we have synthesized and characterized novel boradiazaindacene BODIPY-based dye with bulky substituents (3,5-di-tert-butylphenyl) to prevent π-π stacking of the chromophore. We have succesfully demonstrated that by simple modulation of BODIPY core with very bulky groups lead us to have a bright emissive compounds in solid state. In the second part of this research, we developed BODIPY based near-IR dye as a selective, ratiometric and water-soluble fluorophore for Zn (II) cation. We functionalized the versatile BODIPY from its 3 and 5 positions for long wavelength emission the zinc selective chemosensor.xv, 116 leaves, illustrationsEnglishinfo:eu-repo/semantics/openAccessSolid state fluorescenceChemosensorBoradiazaindaceneNear-IR dyesπ-π stackingStokes’ shiftQP519.9.F56 O93 2010Fluorescent probes.Fluorescence spectroscopy.Fluorescent Dyes.Nanostructured materials.Light emitting diodes.ThesisB122588
