Effect of the anchoring group in porphyrin sensitizers: phosphonate versus carboxylate linkages

Porphyrins are an important family of organic chromophores that have attracted attention as photosensitizers in TiO2-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.

  • As an example, we have shown that the phosphoryl substituted porphyrins are particularly versatile organic precursors for elaboration of functional hybrid organic/inorganic materials having a great variety of structure types.
  • Moreover, as shown in this review, the phosphonate linkage is much less labile that the carboxylate one in various experimental conditions.
  • In another domain the use of the phosphonate anchoring group is challenging to develop efficient multi- electron catalysts that exhibit strong stability in aqueous media.
