Zinc phthalocyanine labelled polyethylene glycol was prepared to track and monitor the in vivo fate of polyethylene glycol. The chemical structures were characterized by nuclear magnetic resonance and infrared spectroscopy. Their light stability and fluorescence quantum yield were evaluated by UV-Visible and fluorescence spectroscopy methods. The interaction of zinc phthalocyanine labelled poly...

Non-precious molecular cobalt phthalocyanine (CoPc) complexes have been considered to be promising electrocatalysts due diversity of substituents and carbon supporting matrixes. Here, we report a highly dispersed fluorinated CoPc (CoPcF16) molecule electrocatalyst immobilized in ordered mesoporous CMK-3 (CMK-3-CoPcF16) via π-π interaction. The is characterized by X-ray photoelectron spectroscop...

A Pt-free cathode catalyst is necessary for proton-exchange membrane fuel cell (PEMFC) to enable the widespread use of these environmentally friendly energy conversion devices at affordable price. Herein, a pyrolyzed electrospun carbon nanofibre (CNF) prepared embedded with cobalt(II) phthalocyanine and iron(II) compounds provide transition metal N4-macrocyclic complex-derived sites (MNX) posse...
