Photoluminescence (PL) properties of crystalline samples of a new paramagnetic organic molecule deposited on different substrates have been studied. Supported by optical absorption and PL spectroscopy in dilute solution, confocal polarized fluorescence microscopy was applied to investigate the supramolecular organization of the obtained structures. Among others, needle-shaped crystals and nanofibers were obtained, showing a high crystalline order along with a strong emission anisotropy demonstrating a preferential direction of the transition dipole moment along their main axis.

Abstract
Photoluminescence (PL) properties of crystalline samples of a new paramagnetic organic molecule deposited on different substrates have been studied. Supported by optical absorption and PL spectroscopy in dilute solution, confocal polarized fluorescence microscopy was applied to investigate the supramolecular organization of the obtained structures. Among others, needle-shaped crystals and nanofibers were obtained, showing a high crystalline order along with a strong emission anisotropy demonstrating a preferential direction of the transition dipole moment along their main axis.
