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.
