Robust and conductive two-dimensional metal−organic frameworks with exceptionally high volumetric and areal capacitance

[Cu3(C6Se6)]n: The First Highly Conductive 2D π–d Conjugated Coordination Polymer Based on Benzenehexaselenolate

“…[1,2] Recently, there are growing interests in design and synthesis of 2D covalent or noncovalent organic materials with in-plane π-conjugation structure. [17][18][19][20][21][22][23][24][25][26][27][28][29] The planar structure of these graphene analogues facilitates the synthesis of benzene-and triphenylene-polyselenols and CPs containing these ligands (relevant results are in preparation).

“…The synthesis of protected BHS hexakis(tertbutylseleno)benzene (t-Bu 6 BHS) was reported by Turner and Vaid in 2012. [17][18][19][20][21][22][23][24][25][26][27][28][29] The planar structure of these graphene analogues facilitates the [33] An alternative approach is Lewis acid promoted deprotection protocol.…”

Structural Engineering of Low‐Dimensional Metal–Organic Frameworks: Synthesis, Properties, and Applications

“…[30][31][32][33][34][35][36][37] Since the discovery of carbon nanotubes (CNTs) in the early 1990s, 1D nanostructures, such as nanowires, nanotubes, and nanorods, have been extensively investigated because of their unique geometrical and electronic characteristics. [48][49][50] These types of MOFs, such as 1D single-walled MOF nanotubes, 1D hexagonal MOF nanorods, ultrathin 2D MOF nanosheets, [51][52][53] have similar morphological features to those of the other 1D or 2D nanomaterials, which endows them with distinctive dimensional-dependent properties including high aspect ratio and abundant accessible active sites. [41][42][43][44][45][46][47] More recently, LD MOFs have attracted intensive interest and been investigated in various applications.…”

Hierarchically Structured Two‐Dimensional Bimetallic CoNi‐Hexaaminobenzene Coordination Polymers Derived from Co(OH)2 for Enhanced Oxygen Evolution Catalysis

“…However, as compared with Co(OH) 2 , numerous structure defects can be seen on the flakes of CoNi‐HAB/Co(OH) 2 in Figure 2g. Moreover, an interlayer spacing of 0.308 nm for Ni‐HAB was detected in HRTEM image of CoNi‐HAB/Co(OH) 2 (Figure 2h), indicating the sacrifice of Co(OH) 2 for the growth of CoNi‐HAB/Co(OH) 2 . To eliminate the interference of CFP on structure characterization, we synthesized Ni‐HAB, Co‐HAB, and CoNi‐HAB through hydrothermal method and their XRD patterns show no characteristic diffraction peaks (Figure S2, Supporting Information).…”

“…Especially, the 2D π‐d CCP based on benzenehexaselenolate can be turned into a highly conductive one with an electrical conductivity of 110 S cm −1 at 300 K . Compared with triphenylene‐based ligands such as 2,3,6,7,10,11‐hexahydroxytriphenylene, 2,3,6,7,10,11‐hexathiotriphenylene, and 2,3,6,7,10,11‐hexaiminotriphenylene, hexaaminobenzene (HAB), as the smallest π‐conjugated ligands, not only exhibits high conductivity and good stability in the honeycomb 2D lattice of CCPs, but also displays highly dense redox‐active sites such as metal‐N‐C and metal‐N 4 . Furthermore, Co‐ or Ni‐based CCPs have been proved to have high catalytic activity for oxygen evolution reactions (OER) by theoretical and experimental studies .…”
