Abstract: An acylated phthalocyanine of the formula: wherein, R1 and R2 are each selected from the group consisting of hydrogen, alkyl, alkoxy and acyl radicals of the formulae —COR and —CRHOH, whereby 1-4 of the 8 R1 and R2 radicals are selected from the group consisting of —COR and —CRHOH, and if R1 or R2 on a benzene ring is selected from —COR or —CRHOH, then the other respective R1 or R2 radical on the benzene ring is hydrogen, R is CH3(CH2)n— where n is 0-15, M is at least one of Mg, Zn, Cd, Cu, Ni, Co, Fe, Pt, Pd or Sn, alkyl is CnH2n+1 where n is 7-14, and alkoxy is OCnH2n+1 where n is 6-15.

Abstract: A method for covalently binding target molecules to carbon nanoparticles via at least one bridge molecule includes converting carbon nanoparticles to acyl carbon nanoparticles using a carbonyl compound of the at least one bridge molecule in the presence of a Lewis acid under Friedel-Crafts conditionsm, where the acyl carbon nanoparticles include a nucleofuge in the omega position. The target molecule is covalently bound to the acyl carbon nanoparticles via nucleophilic substitution of the nucleofuge in the omega position.
