An efficient strategy for building sulfur-bridged oligo-BODIPYs based on the SNAr reaction is described. These oligo-BODIPYs showed broadband and strong visible-near-infrared (NIR) light absorption, strong intramolecular exciton coupling, and efficient intersystem crossing (ISC). Generation of 1O2 as well as O2•- under irradiation was found to give high reactive oxygen species generation efficiencies for those oligomers.
