Replication data of Lotsch group for: "Direct and Linker-Exchange Alcohol-Assisted Hydrothermal Synthesis of Imide-Linked Covalent Organic Frameworks"

Listed in DaRUS

Covalent organic frameworks (COFs) are an extensively studied class of porous materials, which distinguish themselves from other porous polymers in their crystallinity and high degree of modularity, enabling a wide range of applications.

Description

However, the established synthetic protocols for the synthesis of stable and crystalline COFs, such as imide-linked COFs, often requires the use of high boiling solvents and toxic catalysts, making their synthesis expensive and environmentally harmful.

Herein, we report a new environmentally friendly strategy - an alcohol-assisted hydrothermal polymerization approach (aaHTP) for the synthesis of a wide range of crystalline and porous imide-linked COFs. This method allows us to gain access to new COFs and to avoid toxic solvents by up to 90% through substituting commonly used organic solvent mixtures with water and small amounts of n-alcohols without being restricted to water-soluble linker molecules.

Additionally, we use the aaHTP to demonstrate an eco-friendly COF-to-COF transformation of an imine-linked COF into a novel imide-linked COF via linkage replacement, inaccessible using published reaction conditions. This dataset contains all data from analytical measurements including FT-IR spectra (*.csv), raw XRRD patterns (*.xyd), 1H, 13C, 15N NMR spectra (*.csv), Ar sorption isotherms (*.txt), TEM images (*.tif), and simulated COF structure files (*.cif) mentioned under the related publication.

The data from each anaytical measurement is summarized in a folder named with the measurement.
