In this work we report the effect of the polar solvent entrapped on benzyl-nhexadecyldimethylammonium chloride (BHDC) reverse micelles (RMs), as nanoreactors for gold nanoparticles (AuNPs) synthesis. We have evaluated how the room temperature ionic liquid (RTIL) 1-butyl-3-methyl...

The photo-assisted oxygen transfer to cyclohexene, cyclooctene and 1-octene was investigated using molecular O2 as a primary oxidant with a dichloro-dioxo-(4,4?-dicarboxylato-2,2?-bipyridine) molybdenum(VI) complex grafted on the surface of mesoporous TiO2 supports exhibiting dif...

Two phthalocyanines (Pcs) with either a zinc or a ruthenium metal at the center of the macrocycle have been functionalized by a cholesteryl oleate moiety. The potential photosensitizers (PSs) for the treatment of cutaneous leishmaniasis have been studied on their photophysical p...
