Carbon nanotube-templated copper phthalocyanine derivative assemblies via solid-phase synthesis: Effects of hydrogen bond on the structure of the assemblies

Multiwalled carbon nanotube (MWCNT)-templated copper phthalocyanine (CuPc), copper tetrapyridinoporphyrazine (CuTAP), and copper tetrapyrazinoporphyrazine (CuPTpz) assemblies were prepared by a solid-phase synthesis method in a muffle furnace. The as-products were thoroughly characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, differential thermal analysis, Raman spectroscopy, IR, and UV-vis spectrum spectroscopy. The structures of the CuPc derivatives/MWCNTs assemblies strongly depend, on the number of the N atoms in. the backbone of CuPc derivatives. The nanostructure of the CuPc/MWCNTs assembly displays CuPc one-dimensional nanocrystals connected by MWCNTs, the structure of the CuTAP/M WCNTs assembly exhibits a homogeneous CuTAP/MWCNTs nanocomposite, and the structure of CuPTpz/MWCNTs is a coaxial nanotube. It shows that the morphologies and the shapes of MWCNT-templated CuPc derivative assemblies are mainly controlled by the hydrogen bonds between the acid-functionized MWCNTs and the compounds.
