Perfluorinated gallium phthalocyanine F 16 PcGa axially grafted few-layer black phosphorus BP nanosheets F 16 PcGaBP were synthesized by reaction of F 16 PcGaCl with 4-hydroxylbenzenediazonium tetrafluoroborate-functionalized BP 4-HBT-BP. Direct evidence for the formation of a PC bond between phosphorus and 4-hydroxylphenyl in 4-HBT-BP has been observed.
