Substituted 1,3,5-triazine hexacarboxylates as potential linkers for MOFs
Klinkebiel, Arne,Beyer, Ole,Lüning, Ulrich
, (2019)
Hexacarboxylates are promising linkers for MOFs such as NU-109 or NU-110, which possess large values for surfaces and pore volumina. Starting from 2,4,6-tris(bromoaryl)-1,3,5-triazines, palladium-catalyzed cross coupling reactions (Suzuki-Miyaura, Sonogas

Light-driven water splitting is a potential source of abundant, clean energy, yet efficient charge-separation and size and position of the bandgap in heterogeneous photocatalysts are challenging to predict and design. Synthetic attempts to tune the bandgap of polymer photocatalysts classically rely on variations of the sizes of their π-conjugated domains. However, only donor–acceptor dyads hold the key to prevent undesired electron-hole recombination within the catalyst via efficient charge separation. Building on our previous success in incorporating electron-donating, sulphur-containing linkers and electron-withdrawing, triazine (C3N3) units into porous polymers, we report the synthesis of six visible-light-active, triazine-based polymers with a high heteroatom-content of S and N that photocatalytically generate H2 from water: up to 915 μmol h?1 g?1 with Pt co-catalyst, and—as one of the highest to-date reported values ?200 μmol h?1 g?1 without. The highly modular Sonogashira–Hagihara cross-coupling reaction we employ, enables a systematic study of mixed (S, N, C) and (N, C)-only polymer systems. Our results highlight that photocatalytic water-splitting does not only require an ideal optical bandgap of ≈2.2 eV, but that the choice of donor–acceptor motifs profoundly impacts charge-transfer and catalytic activity.

Donor–acceptor dyads hold the key to tuning of electrochemical properties and enhanced mobility of charge carriers, yet their incorporation into a heterogeneous polymer network proves difficulty owing to the fundamentally different chemistry of the donor and acceptor subunits. A family of sulfur- and nitrogen-containing porous polymers (SNPs) are obtained via Sonogashira–Hagihara cross-coupling and combine electron-withdrawing triazine (C3N3) and electron-donating, sulfur-containing linkers. Choice of building blocks and synthetic conditions determines the optical band gap (from 1.67 to 2.58 eV) and nanoscale ordering of these microporous materials with BET surface areas of up to 545 m2 g?1 and CO2 capacities up to 1.56 mmol g?1. Our results highlight the advantages of the modular design of SNPs, and one of the highest photocatalytic hydrogen evolution rates for a cross-linked polymer without Pt co-catalyst is attained (194 μmol h?1 g?1).

Design and synthesis of ordered, metal-free layered materials is intrinsically difficult due to the limitations of vapor deposition processes that are used in their making. Mixed-dimensional (2D/3D) metal-free van der Waals (vdW) heterostructures based on

A new class of discotic liquid crystals based on 2, 4, 6-triphenyl-1, 3, 5-triazine as a core and [(4-alkoxyphenyl)ethynyl] benzene ester as rigid arms has been synthesized by a Pd(O)/Cu(I)-catalyzed carbon-carbon coupling reaction. The obtained compounds exhibited liquid-crystalline properties.
