Two isomers of porphyrin trimer 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 trimer with diarylethyne linkers. Obtained data revealed weak inter-chromophore electronic communication in the ground state but significant exciton coupling whereas the properties of the individual chromophores are mainly retained for triazole-bridged dimer and trimers.
