The catalysis of covalent organic frameworks (COFs) in Li–S chemistry is largely blocked by a weak chemical interaction and low conductivity. Herein, new kind diketopyrrolopyrrole (DPP)-based COF situ fabricated onto the carbon nanotube (CNT) surface (denoted as COF@CNT) to uncover electrocatalysis behavior its strong highly conductive property. We declare that electrocatalytic activity DPP-COF can be maximized introducing an appropriate content CNT (66 wt %); analyses including density...

Carbon dots have wide applications in bioimaging, encryption, sensing, and light-emitting devices, but most preparations of carbon require complicated separation purification steps. Here, a clustering-induced emission luminogen, sodium alginate, was covalently "glued" by ethylenediamine to prepare on 100 g scale, without any or purification. The conversion yield as high 94.7%. Theoretical calculations suggested that the fluorescence as-prepared (N-CDs) mainly attributable through-space...
