    • Abstract

       

      Near-infrared BODIPY photosensitizers with symmetrical 2,6-diiodo 3,5-distyryl 1,2-Bis(2-pyridylmethoxy) benzene were synthesized to study the singlet oxygen (1O2) photosensitizing efficiency astriplet photosensitizer as well as fluorescent sensors for metal cation recognition. Moderate singlet oxygen(1O2) quantum yield (ϕΔ) was obtained for the photosensitizers. Emission intensity of the photosensitizersincreased ca. by 1.4-2-fold upon addition of Hg2+ and Fe2+ ions. The discussed results are useful to designnear-infrared photosensitizers with long lived triplet excited states for various applications such as PDT,fluorescent bioimaging and sensor materials.
