PNS039 Synthesis, spectroscopy and photophysical characterization of two meso-substituted tetramethyl borodipyrromethene (BODIPY) derivatives.

Abstract

Fluorescence is a photophysical process that occurs in some compounds in excited electronic state, in which the return of the excited electron to lower energy orbitals is accompanied by luminescence emission. In the last decades, fluorescence-emitting compounds (fluorophores) have risen as an essential tool for academic and commercial researches; consequently, every year novel fluorescent compounds are synthesized and characterized. Borodipyrromethene (BODIPY) is a widely applied fluorescent scaffold, characterized by two pyrrolic units bridged by a sp2 carbon, and a BF2 unity complexed to the pyrrolic nitrogens. Herein we show the synthesis and characterization of two meso-substituted BODIPYs as a part of a new research project recently implemented in our group.
