Synthesis, crystal structure and physical properties of two new donor molecules

► The first pyridyl group is directly linked to the EDO-TTF group. ► The first 3-pyridyl group is directly linked to the TTF unit. ► The crystal structure of 1 indicates molecule 1 is a bent donor molecule. ► The intramolecular charge transfer from the TTF unit to the pyridine is studied. ► We also compared the electrochemical and spectroscopic properties with other molecules.
