Two rare indium-based porous metal–metalloporphyrin frameworks exhibiting interesting CO2 uptake

Abstract

Two rare indium-based porous metal-metalloporphyrin frameworks (MMPFs), MMPF-7 and MMPF-8, were constructed by self-assembly of In(III) and two custom-designed porphyrintetracarboxylate ligands. MMPF-7 and MMPF-8 possess the pts topology and exhibit interesting CO 2 adsorption properties.

Terms & Conditions of access and use can be found at http:// www.tandfonline.com/page/terms-and-conditions structure; Fluorescence; Hydrogen bond In the last decade, a number of metalloporphyrin based metal-organic frameworks (MOF) have been synthesized[1][2][3][4][5] because of their potential applications in areas such as gas adsorption[6],…”

Metalloporphyrins‐Al3+ porous coordination polymers: Preparations, Characterizations and Catalytic Properties

“…As Table shows, the PCPs display the consistent activities with corresponding metalloporphyrins. In view of single product, it has been proposed that the oxidation of ethylbenzene by PCPs involves the formation of reactive oxometalloporphyrin intermediates . PCP4 displays the best catalytic performance with a good yield of more than 98%.…”

Synthesis, Structure, and Selected Properties of Aluminum-, Gallium-, and Indium-Based Metal-Organic Frameworks

“…The trinuclear IBU is much more abundant in In-MOFs than in Al-MOFs, which could be due to the longer M-O bonds for M = In, that allow for a higher flexibility and less steric hindrance in the coordination environment. The [In(-CO 2 ) 4 ] − IBU is formed when four carboxylate ions act as chelating groups (e.g., in ATF-1 [45] or the metal-metalloporphyrin framework (MMPF)-7 [22]). An InO 8 dodecahedron is formed, which corresponds topologically to a distorted tetrahedral node.…”

“…The tetratopic linkers 5,10,15,20-tetrakis(4-carboxyphenyl)porphyrin and 5,10,15,20-tetrakis(4-carboxybiphenyl)porphyrin were used for the synthesis of the two MMPFs: MMPF-7 and MMPF-8 [22]. In addition to the [In(-CO 2 ) 4 ] − IBUs, further In 3+ ions are coordinated within the porphyrin ring.…”
