为此,本研究提出了异质框架光催化剂的概念,设计了一种MOF@COF(NH2–UiO–66@TFPT–DETH)核–壳异质框架光催化剂,用于可见光下的光催化产氢。利用具有规整结构的NH2–UiO–66作为内核,诱导具有较好水稳性的腙键连接的COF TFPT–DETH外壳的生长。通过MOF的末端氨基和COF的醛基之间的席夫碱反应,可得到共价连接的异质...
Thus, these results open a way toward designing 3D stimuli-responsive functionalized COF materials and promote their potential application as drug carriers in the field of disease treatment.doi:10.1002/smll.202102630John Wiley & Sons, LtdSmall

Significantly, comparing with the poor catalytic durability (30 min) of [Ir-ppy], the COF/[Ir-ppy] catalyst still be active after irradiation of 7 h. The extended catalytic reactivity may result from the promoting dispersion of [Ir-ppy] on NAHN-Tp COF which restrains the aggregation-...
When illuminated with visible light, the Pt-doped COF continuously produces hydrogen from water without signs of degradation. With their precise molecular organization and modular structure combined with high porosity, photoactive COFs represent well-defined model systems to study and adjust the molecular...
Herein, we report the design and construction of a new hydrazone-linked chiral COF, termed BtaMth COF, from a chiral hydrazide building block (Mth) and present a one-pot synthetic method for the fabrication of BtaMth@SiO 2 composite for HPLC separation of isomers. The as-synthesized BtaMt...
This work demonstrates an effective and simple approach to the fabrication of hydrazone COF aerogels and additive manufacturing to produce hydrazone COFs of desired shape.doi:10.1002/chem.202302304Ajnsztajn, AlecHarikrishnan, Vijay Vedhan Jayanthi...
Herein, one N-acylhydrazone-linked COF (H-COF) was converted into a stable and π-conjugated oxadiazole-linked COF via post-oxidative cyclization. Both chemical stability and π-electron delocalization throughout the reticular framework are significantly improved, leading to a high hydrogen evolution ...
