The relationship between the aryl substitution pattern and the photophysical and electrochemical properties of the dyes was investigated using experimental and computational methods. It was found that electron-donating & pi;-conjugated groups at the meso position and electron-accepting & pi;-conjugated groups at the C3/C5 position led to blue-shifted spectra, while the opposite substitution pattern resulted in red-shifted spectra. Additionally, inductive electron-donating alkyl groups at the meso position produced a blue spectral shift and an alkyl group at the meso position significantly increased the fluorescence quantum yield compared to the arylated counterparts. Computational investigations revealed that a thioanisyl group at the C3/C5 position resulted in a significantly narrow band gap. These results provide valuable insights into the design and development of new BODIPY dyes with tailored properties for various applications.eninfo:eu-repo/semantics/closedAccessBodipySuzuki CouplingArylated BodipySpectral ShiftsDft StudyPhotophysical PropertiesArticle1291WOS:0010341373000012-s2.0-85163825889N/A10.1016/j.molstruc.2023.135962Q2
