Abstract Growing global concerns over energy security and climate change have intensified efforts to develop sustainable strategies for electrochemical CO 2 reduction (eCO RR). Covalent Organic Frameworks (COFs) emerged as promising electrocatalysts eCO RR due their tunable structures, high surface areas, abundance of active sites. However, the performance 2D COFs is often limited by layer stacking, which restricts site exposure reduces selectivity. To overcome these challenges, a new class...
Incorporating an aggregation-induced emission (AIE) effect into polymers will lead to intriguing solid-state fluorescent materials (i.e., AIE-active polymers) that have great potential in optoelectronics and sensing applications. In this work, a series of polyimine vitrimers (TPE-PIs), containing different loadings tetraphenylethene (TPE) moieties, been successfully prepared where monomers are chemically integrated the PI network, either as side chains or backbone polymer network. The...
As a proof-of-concept study, Imi-cage and Phos-cage organic molecular cages (OMCs) containing the triphenylphosphine (TPP) moiety, nonclassic AIE luminogen (AIEgen), have been designed to demonstrate cage-confinement induced emission enhancement (CCIEE). Thanks confinement effect of OMCs, rigid exhibits much higher photoluminescence (PL) quantum yield (ΦPL) than open-shell Semicage small molecule TPP in both solution amorphous solid states. The could be further enhanced crystalline state...
Two-dimensional covalent organic frameworks (COFs) are ideal electrode materials for electrochemical energy storage devices due to their unique structures and properties, the accessibility utilization efficiency of redox-active sites in COFs matters deciding pseudocapacitive performance. Via introducing meticulously designed phenolic hydroxyl (Ar-OH) groups with hydrogen-bond forming ability onto imine COF skeletons, DHBD-Sb-COF exhibited improved hydrophilicity crystallinity than parent...
Group 5A triphenyl compounds with coordination ability such as triphenylamine (NPh3) and triphenylphosphine (PPh3) have been widely investigated for the construction of functional porous organic materials. In this work, a SbPh3-based molecular cage (Sb-cage) was unprecedently synthesized. The spatial configuration Sb-cage precisely analyzed by X-ray single crystal diffraction, showing double pyramid [2+3] assembly. employed to mediated-growth palladium nanoparticles (PdNPs) an average...
The feasible preparation of Pd catalysts, one the most widely used with high performance and easy recovery still remains greatest challenge. Covalent triazine-based frameworks (CTFs), by virtue strong covalent linkages abundant nitrogen atoms, have been deemed as a central subclass porous supports for nano-functional materials including metal nanocatalysts. Herein, series CTF1s prepared ionothermal synthesis followed rearrangement at higher temperatures (500~900 °C). CTF1s-immobilized...
