Gas Sorption Properties of Isostructural Co-MOFs Containing Dipyridylporphyrin Linkers with Different Substituents at the 10,20-meso-Positions

N-doped porous carbons derived from Zn-porphyrin-MOF

N-doped porous metal-organic framework (MOF)-derived carbons (MDCs) were directly synthesized from a new Zn-DpyDtolP-MOF (ZnDpyDtolP·1/2DMF, H2DpyDtolP = 5,15-di(4-pyridyl)-10,20-di(4-methylphenyl)porphyrin) containing a 3D hexagonal network through a self-templated carbonization method. KOH-activated MDC derivatives denoted as MDC-700-nKOH were also prepared with different weight ratios of KOH activator to MDC (MDC : KOH = 1 : n, where n = 1, 2). Compared to bare MDC, MDC-700-nKOH showed effective improvements of both gas sorption and electrochemical capacitive properties. More developed microporosity by KOH activation might induce great enhancement of high operating capacitive performances. The N-doped MDC-700-2KOH had high maximum gravimetric specific capacitance (555.6 F g-1) and specific energy (40.4 W h kg-1) at 0.1 A g-1 in 1 M H2SO4. Even at a high current density of 190 A g-1 in 6 M KOH, it exhibited high capacitive performance with a large specific power of 80 423 W kg-1. MDC-700-nKOH electrodes also showed good recycling properties of electrochemical capacitance up to 30 000 cycles.

Novel meso-substituted trans-A2B2 porphyrins: synthesis and structure of their metal-mediated supramolecular assemblies

Five novel trans-A₂B₂ porphyrins and their corresponding coordination polymers with transition metals have been synthesized. Absorption and emission studies and structural investigations define the coordination patterns of these compounds in the solid state.

Porphyrinic metal–organic frameworks from custom-designed porphyrins

This paper highlights porphyrinic metal–organic frameworks (porph-MOFs) assembled from metal ions and custom-designed porphyrins: pyridyl-based, carboxyphenyl-based porphyrins and other custom-designed porphyrins.
