Abstract
The X-ray structure and single-crystal spectra of monoclinic and triclinic dimorphs of a squarylium dye are reported. Crystal polymorphism is shown to be an effective approach for studying excitation energy transfer in crystals. The long-axis-polarized transition leads to quasi-metallic reflection bands which cannot be fitted by molecular polariton calculations in the point-dipole approximation.
