Stable photoactive organogels were successfully prepared by a two-step sequence involving: 1) formation of thermoreversible organogels by use of a combination of low-molecular-weight organogelators (LMOGs) and ZnII-phthalocyanine (ZnII-Pc) moieties containing complementaryorganogelatorstructures, and 2) strengthenhancement of the gels by in situcross-linking with the aid of CuI-catalysed azide-alkyne

The synthesis and photophysicalproperties of several fullerene–phthalocyanine–porphyrintriads (1–3) and pentads (4–6) are described. The three photoactive moieties were covalently connected in an one‐step synthesis through 1,3‐dipolar cycloaddition to C60 of the corresponding azomethine ylides generated in situ by condensation reaction of a substituted N‐porphyrinylmethylglycine derivative and an

asymmetrical, push–pull phthalocyanine bearing bulky tert-butylcarbazolyl moieties as electron donor and carboxylic acid as anchoring group was synthetized and tested as a photosensitizer in dye-sensitizedsolarcells (DSSC). The new photosensitizer was characterized by 1H and 13C NMR, UV–Vis and mass spectrometry. The bulky tert-butylcarbazolyl moieties avoid the aggregation of the phthalocyanine dye. DFT studies

Zinc(II) phthalocyanine dyes that contain triarylamine‐terminated bisthiophene and hexylbisthiophene groups have been synthesized by a convergent approach by using carboxytriiodo–ZnPc as a precursor. Further transformation of the iodo groups by a Pd‐catalyzed reaction allowed easy preparation of further extended π‐conjugated carboxy–ZnPcs. These dyes have been used as sensitizers in dye‐sensitized
