Abstract: Porphyrins are an important family of organic chromophores that have attracted attention as photosensitizers in TiO_2-based dye-sensitized solar cells (DSSCs). This brief review is dedicated to comparative studies of phosphonic and carboxylic acid anchoring groups for attachment of porphyrin sensitizers on semiconductors or conductors surface. Here we have selected some representative examples of recently described phosphonate/carboxylate porphyrins with the aim to demonstrate that porphyrin phosphonate should be a promising anchoring group for such systems.
