Synthesis and characterization of nanosized polycarboranyl-porphyrazine conjugates

摘要

The synthesis and characterization of a highly boronated porphyrazine, 2,3,7,8,12,13,17,18-octakis-[6-(2-(1′-methyl-1′,2′-dicarba-closo-dodecaboran-2′ -yl)hexyl)-1,2-dicarba-closo-dodecaboran-1-yl)hexylthio] 5,10,15,20 (21H, 23H) porphyrazine (H2(MCHE)CHESPz), is reported. This nanosized molecule bears eight dicarboranyl-substituted carborarod-like alkyl pendants and, as such, represents a rare example, if any, of a tetrapyrolic system bearing 160 boron atoms per molecule, corresponding to 40% boron content by weight.
