Covalent Triazine Frameworks via a Low‐Temperature Polycondensation Approach
Covalent triazine frameworks (CTFs) are normally synthesized by ionothermal methods. The harsh synthetic conditions and associated limited structural diversity do not benefit for further development and practical large-scale synthesis of CTFs. Herein we report a new strategy to construct CTFs (CTF-HUSTs) via a polycondensation approach, which allows the synthesis of CTFs under mild conditions f...
متن کاملModelling analysis of the structure and porosity of covalent triazine-based frameworks.
Varying degrees of order have been found experimentally for a series of covalent triazine-based frameworks (CTFs) when synthesised under different reaction conditions. Here, we use molecular modelling to discuss the potential origins of this structural order by analysis of the node and strut building blocks. We use a combination of small model structures based on DFT optimised monomer units and...
متن کاملHigh adsorptive properties of covalent triazine-based frameworks (CTFs) for surfactants from aqueous solution.
Carbonaceous covalent triazine-based frameworks from 1,4-dicyanobenzene (CTF-1) can adsorb up to about 4 g g(-1) of the surfactants alkyl polyglycolether, C12EO7 and sodium dodecylsulfate, SDS from aqueous solution (c = 8.0 mmol L(-1)) which is more than 20-times the gravimetric uptake capacity of a carbon black (Printex L from Evonik). This high uptake is due to CTF sheet exfoliation. Taking i...
متن کاملThiophene-based covalent organic frameworks.
We report the synthesis and characterization of covalent organic frameworks (COFs) incorporating thiophene-based building blocks. We show that these are amenable to reticular synthesis, and that bent ditopic monomers, such as 2,5-thiophenediboronic acid, are defect-prone building blocks that are susceptible to synthetic variations during COF synthesis. The synthesis and characterization of an u...
متن کاملAn Efficient and Environmentally Benign Chemical Synthesis of Testolactone
Testolactone was obtained commercially by microbial transformation of either testosterone or progesterone and also synthetically, albeit in low yield. The only chemical synthesis of 1 so far described in the literature starting from dehydroepiandrosterone (2) is shown in Scheme 1. The strategy followed in this synthetic approach consisted in the initial formation of the lactone ring by a Baeyer...
