Cof linker
WebHowever, the linker exchange method has so far only been described for COFs with relatively weak linkages, like imines. Herein it is shown that this method can be also used for a post-synthetic linker exchange reaction on a ß-ketoenamine linked COF. The time needed to achieve considerable linker exchange is much prolonged compared to other ...

WebMar 9, 2024 · Lu et al. designed dioxin-linked metallophthalocyanine COFs with metal catalytic activity sites (MPc-TFPN COF; M=Ni, Co, Zn) to achieve CO 2 emission reduction through electrochemical transformation. NiPc/CoPc-TFPN COF showed excellent Faradaic efficiency of CO (FE CO ) = 99.8 (±1.24) %/ 96.1 (±1.25) % [ 7 ]. WebThese two COFs were further facilely developed as efficient photocatalytic platforms for the synthesis of thiophosphinates. Py-DMTA-COF exhibited better photocatalytic activity, broad substrate applicability, and excellent recycling capacity for the preparation of thiophosphinates from P(O)H compounds and thiols compared to Py-DMTPDA-COF.
