Synthesis and photoconductivity study of carbon nanotube bonded by tetrasubstituted amino manganese phthalocyanine

The multiwalled carbon nanotube (MWCNT) bonded by 2,9,16,23-tetra amino manganese phthalocyanine (TAMnPc) was obtained and both its chemical and aggregated structures were characterized by means of FTIR, UV-Vis, TEM, and XRD. The photoconductivity of single-layered photoreceptors, where MWCNT bonded by TAMnPc (MWCNT–TAMnPc) served as the charge generation material (CGM), was studied by the xerographic photodischarge method. The photosensitivity of MWCNT–TAMnPc was better than that of pristine TAMnPc and MWCNT–TAMnPc composite obtained by physical blending. It is the photoinduced charge transfer from TAMnPc to MWCNT in MWCNT–TAMnPc that contributes to the higher photosensitivity of MWCNT–TAMnPc.
