“…[82] Thes tructures of the Co and Ni 2D catecholate MOFs were established by X-ray crystallography and highresolution transmission electron microscopy (HR-TEM). Both the Co-and Ni-based MOFs display permanent porosity,w ith BET surface areas of 490 and 425 m 2 g À1 , respectively.Although the electrical properties of the Ni and Co materials were not reported, single crystals of ar elated material synthesized from Cu II and H 6 HHTP exhibit ac onductivity of 0.2 Scm À1 (four-probe) at room temperature.…”

Owing to their outstanding structural, chemical, and functional diversity, metal-organic frameworks (MOFs) have attracted considerable attention over the last two decades in a variety of energy-related applications. Notably missing among these, until recently, were applications that required good charge transport coexisting with porosity and high surface area. Although most MOFs are electrical insulators, several materials in this class have recently demonstrated excellent electrical conductivity and high charge mobility. Herein we review the synthetic and electronic design strategies that have been employed thus far for producing frameworks with permanent porosity and long-range charge transport properties. In addition, key experiments that have been employed to demonstrate electrical transport, as well as selected applications for this subclass of MOFs, will be discussed.

“…The nanorod-shaped MOF, termed as nickel catecholate framework (Ni-CAT) was prepared by 2,3,6,7,10,11-hexahydroxytriphenylene (H 12 C 18 O 6 , HHTP) linked with Ni(II) in an aqueous solution without any modulator. 25,26 Nanorod-shaped nanoporous carbon with high specic surface area was obtained by shape-preserved thermal transformation of Ni-CAT. The nanoporous carbon nanorods were demonstrated to have good capacitive performance as supercapacitor electrode materials.…”

Self-template construction of nanoporous carbon nanorods from a metal–organic framework for supercapacitor electrodes

The morphologies and structures of nanostructured carbons generally influence their catalysis, electrochemical performance and adsorption properties. Metal-organic framework (MOF) nanocrystals usually have various morphologies, and can be considered as a template to construct nanostructured carbons with shaped nanocubes, nanorods, and hollow particles by thermal transformation. However, thermal carbonization of MOFs usually leads to collapse of MOF structures. Here, we report shape-preserved carbons (termed as CNRods) by thermal transformation of nickel catecholate framework (Ni-CAT) nanorods. Supercapacitors of CNRods treated at 800 C were demonstrated to have enhanced performance due to their structural features that facilitate electron conduction and ion transport as well as abundant O content benefiting the wettability of the carbon materials. This may provide a potential way to explore novel carbon materials for supercapacitors with controllable morphologies and high capacitive performance.

“…These include the family of metal catecholate frameworks of Ni II and Co II constructed from hexahydroxytriphenylene (H 6 HHTP), which consist of 2D sheets layered between discrete HHTP complexes. 40 More recently, the groups of Nishihara and Dinc ă have reported the 2D MOFs [Ni 3 (BHT) 2 ] (BHT = benzenehexathiol) 41 a conductivity of 1580 S·cm -1 -a record value at room temperature. 44 A number of related 2D MOFs have subsequently been reported, 45 and their range of applications have been expanded to include electrocatalysis 46 -49 and chemiresistive sensing.…”
