Abstract
Dyads of a N-confused porphyrin (NCP) moiety covalently linked to a porphyrin free-base (H2P) or a zinc(II) porphyrinate (ZnP) moiety via a flexible alkyl chain of variable length have been synthesized. Photoluminescence study demonstrated an efficient excitation energy transfer from H2P/ZnP moiety to the NCP moiety. Measurement of the near-IR emission of singlet oxygen produced by these dyads via photosensitization showed that the NCP-ZnP dyads (F{cyrillic}Δ = (0.61-0.65) ± 0.13) were better 1O2 generators than the NCP-P dyads (F{cyrillic}Δ = (0.36-0.41) ± 0.08).
