Synthesis and Electric Properties of a Two‐Dimensional Metal‐Organic Framework Based on Phthalocyanine

Abstract

Complexation of copper(II) 2,3,9,10,16,17,23,24-octahydroxy-29H,31H-phthalocyanine (CuPcOH) with copper(II) ions gives a two-dimensional (2D) metal-organic framework (MOF). This is the first report of a phthalocyanine-based MOF. This 2D MOF was obtained as a black powder and showed an electrical conductivity of 1.6×10 S cm at 80 °C. When this MOF is used as a cathode of lithium ion battery (LIB), large charge/discharge capacities of 151/128 mAh g were obtained. In addition, it showed a good stability during 200 charge/discharge cycles. The obtained LIB performance mainly originates from the electrically conductive and redox-active framework of the phthalocyanine-based 2D MOF and its hierarchical microporous/mesoporous structure.

“…Thesuccessful preparation of PcCu-O 8 -Co was confirmed by Fourier transform infrared (FTIR) spectroscopy and powder X-ray diffraction (XRD) measurements (Figure 1b and Figure S1). [32] TheXRD pattern of PcCu-O 8 -Co reveals ahighly crystalline structure with prominent (100), (110), (200), and (001) peaks at 5.18 8,7 .28 8,1 0.18 8,a nd 27.58 8, respectively ( Figure 1b).

“…Thepeak of the C-O stretching vibration shifts from 1288 (C-O-H) in the monomer (PcCu-(OH) 8 )to1270 cm À1 (C-O-Co) in PcCu-O 8 -Co due to CoÀOb ond formation and is accompanied by the disappearance of the peak of the C-O-H bending mode at 630 cm À1 . [32] TheXRD pattern of PcCu-O 8 -Co reveals ahighly crystalline structure with prominent (100), (110), (200), and (001) peaks at 5.18 8,7 .28 8,1 0.18 8,a nd 27.58 8, respectively (Figure 1b). These intensive peaks indicate that PcCu-O 8 -Co exhibits long-range order within the ab plane and layer stacking structure along the c direction (001).…”

Metal-organic framework functionalization and design strategies for advanced electrochemical energy storage devices

“…Co-HAB also demonstrates remarkable performance at high rates (up to 12 A g −1 ) and the ability to recover capacity when returned to more moderate cycling rates. Effective cycling at high charge/discharge rates was also demonstrated by another moderately conductive MOF (Cu-CuPc, reported conductivity 1.6 × 10 −6 S cm −1 ) that was able to achieve~150 mAh g −1 at a rate of 5.2 A g −1 for LIB cycling 45 . These examples demonstrate that with the appropriate design features, MOFs have the potential to withstand extraordinary cycling conditions.…”
