Covalent Organic Frameworks (COFs) Pyrene Ligand

A tectonic bridging ligand linker for COFs in applications of effective photo-reductive dehalogenation of phenacyl bromide derivatives and enantio-selective α-alkylation of aldehydes


4,4',4'',4'''-(Pyrene-1,3,6,8-tetrayltetrakis(ethyne-2,1-diyl))tetraaniline (TAEPy) contains a pyrene core with four 4-ethynylaniline side arms at 1,3,6,8-positions. 1,3,6,8-tetrakis(4-aminophenyl)pyrene is mainly investigated in covalent organic frameworks (COFs) for its superb properties such as large surface area, high crystallinity, excellent stability, and good photoelectric activity.

Covalent organic framework COF-JLU22, prepared from TAEPy and an electron-deficient linker 4,7-formyldiphenylbenzo[c][1,2,5]thiadiazole (FDPBT), possessed robust thermal, chemical and photochemical stability, apart from its large pore volume and high crystallinity. Being an electron donor–acceptor type COF, JLU22 is relatively red-shifted in absorption wavelength to enhance the photocatalytic activity of the resulting COF. COF-JLU22 is highly efficient for dehalogenation of phenacyl bromide derivatives and effectively photo-catalyse the enantio-selective α-alkylation of aldehydes.
