Anchor groups play a critical role in attaching the chromophores to semiconductor surfaces in photocatalysts and Dye-Sensitized Solar Cells (DSSCs). Introducing a strong anchor group that also improves the charge injection and controls orientation and binding mode continues to be a challenge in this area. Herein, we introduce the 2-hydroxy isophthalic acid group, as a novel group for anchoring the dye to the TiO2 nanoparticles. The binding of this anchor group was studied and compared to isophthalic acid and 1,3-phenylenebis(phosphonic acid) anchor groups. Moreover, for comparing the effect of the footprint size on binding to the TiO2, two novel tripod and bipod dyes with phosphonic acid anchor groups were synthesized and their binding on TiO2 was studied and compared
