(A) Results of NMR spectroscopy performed after the synthesis of mannose-conjugated porphyrin (man-porph), as described in Fig. 1. Mass spectrometry of mannose-conjugated porphyrin was not performed due to its high polarity. (B) UV-visible absorption spectrum of mannose-conjugated porphyrin showed that it absorbed light of wavelengths ranging from 425 to 450 nm.
