This system has potential applications in photodynamic therapy owing to macrocyclic aromaticity being selectively induced by protecting group removal and strong absorption bands produced in the NIR region especially in methanol.Royal Society of Chemistry2020-07-28engjournal articleAMhttp://hdl.handle.net/2115/82294https://doi.org/10.1039/d0ob01213k1477-0520Organic & biomolecular chemistry182853345338https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/82294/1/Manuscript_obc_revised.pdfapplication/pdf671.25 KB2020-07-28
