D–A–π–A Fused Pentacyclic Organic Dyes as Sensitizers for Dye‐Sensitized Solar Cells Operating under Low‐Light Conditions

ChemistrySelect, Volume 11, Issue 30, 10 August 2026.
The highly conjugated [1]benzothieno[3,2‐b]thieno[2,3‐f][1]benzothiophene (TBTBT) moiety was introduced for the first time as a mild donor group in the structure of three D‐A‐π‐A organic dyes. The compounds were prepared through appropriate multistep synthetic sequences and fully characterized. Dye‐sensitized solar cells fabricated with the new dyes as
