Figure 17.5 Skeleton structures of (a) polypyrrolic photosensitizers (i) porphyrin, (ii) chlorine, (Hi) bacteriochlorin, (iv) phthalocyanine, (v) naphthalocyanine, (vi) texaphyrin (b) examples of metalloderivatives (c) photosensitizers incorporating the metallodrug moieties (x-xii) cisplatin- and/or carboplatin-like structures, (xiii) iron sulphur nilrosy cluster...

Krasnovsky et al. reported the first visible luminescence derived from singlet oxygen produced by protoporphyrin photosensitization in solution. Along with the "monomol" luminescence at 1270 nm, visible luminescence with intensity proportional to the square of the excitation power was observed. Certain compounds such as naphthalocyanines and phthalocyanines give luminescence with extremely high efficiency one of the most effective is tetra-r rr-butyl phthalocyanine (Pc). The spectrum of the... 

A different approach led to the development of a theranostic platform with a single photothermal and photodynamic reagent [147]. Silicon 2,3-naphthalocyanine bis(trihexylsilyloxide) was used as a photosensitizer. The hydrophobic silicon naph-thalocyanine was immobilized (via jr-jr-stacking) on water-dispersible graphene...
