MOFs containing a linear bis-pyridyl-tris-amide and angular carboxylates: exploration of proton conductivity, water vapor and dye sorptions

Abstract

Four new MOFs were shown to have appreciable proton conductivities, selective adsorption of water vapor over nitrogen and a tendency to selectively adsorb cationic dyes such as methylene blue and crystal violet.

Isostructural NiII Metal–Organic Frameworks (MOFs) for Efficient Electrocatalysis of Oxygen Evolution Reaction and for Gas Sorption Properties

“…[50] However,m any MOFs are moisture sensitive given the sensibility of the metal coordination bond or metal oxide cluster which makes them unusablef or water sorptions tudies. [53][54][55][56][57] To date some MOFs have been shown to be water adsorbersa nd some MOFs have been found to be OER catalysts. Recently,o ur group and othersh ave shownt hat, MOFs or PCPs containing ligands with hydrophilic functional groups such as amides and imidazoles or oxygen and nitrogen-rich ligands can function as better candidates for creating hydrophilic channels andt hereby appreciable water sorptionr esults.…”

Characterization of Proton Dynamics for the Understanding of Conduction Mechanism in Proton Conductive Metal‐Organic Frameworks

“…[9][10][11][12][13][14][15][16] The rational design strategies for proton-conductive MOFs are established depending on the proton sources. For example, there are design strategies focusing on the increase in mobile proton concentration and possible conduction pathway through i) countercation inclusion in anionic frameworks type, [17][18][19] where H 3 O + , Me 2 NH 2 + , or NH 4 + are playing a proton source, ii) metal/ligand functionalization by predesign or post-synthetic modification of the MOF type, [20][21][22][23][24][25][26][27] where non-coordinated addition functional groups (-NH 2 , -OH, -PO 3 H 2 or -SO 3 H) provide proton or conduction pathway, iii) acid (H 2 SO 4 , H 3 PO 4 , HCl, etc.) or functional guest molecules (imidazole, triazole, and histamine) inclusion type, [28][29][30] iv) defect control (metal center or ligand missing) type, [31][32][33] and v) external stimulus [34][35][36] such as pressure and light.…”

Tailoring Coordination Polymers by Substituent Effect: A Bifunctional CoII‐Doped 1D‐Coordination Network with Electrochemical Water Oxidation and Nitroaromatics Sensing

“…Further, the presence of coordination unsaturation in CPs was also shown to be of utility for oxygen evolution reactions upon doping of Co II . In furtherance of our efforts in synthesizing CPs with amide functionalities and exploring their properties, herein, we wish to present our studies on the Cd II CPs of tripodal ligand L in combination with substituted isopthalates and exploration of their functional properties. Further, we would like to explore how the substitution of coordination innocent functional groups, such as azido, nitro and bromo on isophthalates influences the geometry of the networks and therefore their functional properties.…”
