Molecules on the base of 1,3-diphenylisobenzofuran attract an interest because of their
possible efficiency for singlet fission This study is focused on electrochemical behaviour of
the „quasi dimer“ of 1,3-diphenylisobenzofuran. For characterization of reduction mechanism
in situ UV-vis and EPR spectroscopy were used. The monomer 1,3-diphenylisobenzofuran
and its CH2 dimer were added to this study for comparison. The redox properties of both
compared molecules are similar. The location and the nature of the covalent bridging unit in
CH2dimer have small effect onthe redox potentials. But the pi-conjugation in the molecule of
quasi dimer causes approximately 0.2 V easier oxidization and reduction.
