Including <jats:bold>MPBTCA<\/jats:bold>, which is a known compound, the seven BODIPY dyes have been characterized by varied physical methods, such as UV\/Visible absorption spectroscopy, low energy photo\u2010electron spectroscopy (AC\u20102), and HOMO\u2010LUMO DFT\/TDDFT calculation. All seven BODIPY dyes have absorption <jats:italic>\u03bb<\/jats:italic><jats:sub>max<\/jats:sub> around 535\u2013545\u2005nm, which is significantly longer than 499\u2005nm of 4,4\u2010difluoro\u20101,3,5,7,8\u2010pentamethyl\u20104\u2010bora\u20103<jats:italic>a<\/jats:italic>,4<jats:italic>a<\/jats:italic>\u2010diaza\u2010<jats:italic>s<\/jats:italic>\u2010indacene (<jats:bold>PM\u2005546<\/jats:bold>). Having structural variation on donor group, acceptor group, donor \u03c0\u2010spacer, acceptor \u03c0\u2010spacer, and the substituent on boron, some BODIPY dyes exhibit small extinction coefficients or spectral integrals in solution (<jats:bold>MPCtBTCA<\/jats:bold>, <jats:bold>MPBT\u2010pyO<\/jats:bold>, <jats:bold>MPBTT\u2010pyO<\/jats:bold>, <jats:bold>MTBTCA<\/jats:bold>), broadening absorption spectral profile (<jats:bold>MTBTCA<\/jats:bold>), weak intramolecular charge transfer characteristics (<jats:bold>MPBT\u2010pyO<\/jats:bold>, <jats:bold>MPBTT\u2010pyO<\/jats:bold>, <jats:bold>MTBTCA<\/jats:bold>), too low LUMO energy level (<jats:bold>PPBTCA<\/jats:bold>), or insufficient dye\u2010uptake by TiO<jats:sub>2<\/jats:sub> FTO (<jats:bold>MPBT\u2010pyO<\/jats:bold>, <jats:bold>MPBTT\u2010pyO<\/jats:bold>, <jats:bold>MTBTCA<\/jats:bold>). Two of the seven BODIPY dyes, <jats:bold>MPBTCA<\/jats:bold> and <jats:bold>MPBTTCA<\/jats:bold>, do not show the adverse properties like other BODIPY dyes.
