isomers of porphyrintrimer with 1,4-diaryltriazole linkers have been synthesized using "click" methodology and characterized by MS, NMR and UV-vis spectroscopy. The porphyrin compounds were shown to exhibit photostability and high solubility. Photophysical data were compared with corresponding ones of synthesized triazole-bridged dimer with the same electronic surrounding and known linear dimer and

dendritic fulleropyrrolidine bearing two pending porphyrins are reported. Both the dendron and the fullerene derivatives were synthesized by CuI‐catalyzed alkyne–azide cycloaddition (CuAAC). The electron‐donor–acceptor conjugate possesses a shape that allows the formation of supramolecular complexes by encapsulation of C60 within the jaws of the two porphyrins of another molecule. The interactions between

We report herein the preparation of two novel porphyrins substituted with an azido group born either on the para-position of one phenyl meso-susbtituent of a tetraaryl zinc porphyrin (1) or directly on the meso-position of a trisaryl nickel porphyrin (2). We studied the scope and the limitation the Huisgen cycloaddition reaction of these two porphyrins using different catalytic conditions. We observed that the carbene (SlMes)CuBr in THF/H2O 3:1 at 45 degrees C for 60 h gives almost quantitative yields for the reaction between I and different alkynes, but significantly lower yields with 2 probably due to its thermal instability.
