N2 - A chlorophyll (Chl) derivative inserting an ethynylene group between the carboxy moiety and chlorin π-skeleton was prepared via copper-mediated propargylic alcohol synthesis and phased oxidation reactions from a 3-ethynyl-Chl-a derivative. The optical and electrochemical properties were investigated by the measurement of ultraviolet–visible absorption spectra and cyclic voltammograms. Its photosensitizing efficiency in dye-sensitized solar cell was evaluated on a titanium oxide semiconductor, and the effect of the inserting linker was described based on the experimental and theoretical studies.
