An investigation of the roles furan versus thiophene π-bridges play in donor–π-acceptor porphyrin based DSSCs [PDF]

, 2018
Dye-sensitized solar cells (DSSCs) continue to attract interest due to their lower cost production compared to silicon based solar cells and their improving power conversion efficiencies. Porphyrin-based sensitizers have become an important sub-class due

4,4″-Dichloro-4′-(2-thienyl)-2,2′:6′,2″-terpyridine

Molbank, 2019
A new thiophene-substituted terpyridine derivative has been prepared and characterized. This ligand features a thiophene heterocycle (as an electrochemically polymerizable unit) as well as two chlorine atoms for further functionalization.
