Improved bipolar properties of ester‐functionalized discotic diimine‐dithiolene complexes

Résumé

A series of platinum diimine-dithiolene complexes with a 5,6-dihydro-1,4-dithiin-2,3-dithiolato (dddt2-) dithiolene ligand and bipyridine carrying tris-alkoxyphenyl fragments connected through an ester linker (bpyCn, n = 8, 12, 16, 10(s), 20) (Scheme 1) has been developed. The mesomorphic properties the ligands have investigated by combination DSC, POM SAXS analyses. were found to self-organize into columnar mesophases hexagonal symmetry over large temperature range including room temperature. Their electronic also characterized electrochemistry, absorption emission spectroscopy measurements TD-DFT calculations. Besides being liquid crystalline, these compounds can undergo two oxidation processes reduction in fully reversible manner, allowing isolation stable dicationic dianionic species. Such behavior is highly promising for development ambipolar semiconducting soft materials.
