Abstract:The physicochemical and luminescent properties of tetrapyrrole macrocycles, such as the porphyrins (H 2 P) and phthalocyanines (H 2 Pc), were preserved by trapping or bonding these species in silica matrices. The method involved used hydroxy-aluminium tetrasulphophthalocyanine OH(Al)TSPc as a probe to find optimal conditions for the entrapment of tetrapyrrole molecules. This methodology made possible the trapping or fixing of macrocyclic species or their respective complexes in the interior of pores existing i… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
