Sulphur-Atom Positional Engineering in Perylenimide: Structure-Property Relationships and H-aggregation Directed Type-I Photodynamic Therapy

This work unveils an S-atom positional engineering strategy generating distinct condensed state emitters with high Φ PL of 0.85 in aqueous media, rare supramolecular assembly, specific type-I photosensitizers, and H-aggregation directed selective PDT.
