The spectral and photophysical properties of indigo derivatives with di-, tetra-, and hexa-substitution in their neutral (keto) form are investigated in solution. The study comprises absorption and emission spectra, together with quantitative measurements of quantum yields of fluorescence (φF) and singlet oxygen formation (φΔ) and fluorescence lifetimes. The energy difference between the HOMO and LUMO orbitals ...
