Cyanine platelet single crystals: growth, crystal structure and optical spectra

Micro transmittance spectroscopy of ultrathin crystalline organic salt semiconductors reveals strong low-energy and weak high-energy bands polarized along the crystallographic b- and c-axis. While the excitonic coupling pattern explains the occurrence of polarized bands, the observed intensities are opposite of expectations based on chromophore alignment within the crystal.
