A sustainable strategy for the visible-light-driven facile N-formylation of amines using a Co(ii)-embedded covalent organic framework as an efficient photocatalyst

Abstract

To date, to tackle the increased greenhouse effect, the development of efficient porous adsorbents to enable rapid atmospheric CO2 uptake capacity is one of the new concerns in environmental remediation....

Sunlight induced efficient photocatalytic oxidation of benzylamines and CO2 reduction over a 2D–2D MoS2/FP-BTA heterojunction catalyst

“…2a is attributed to the existence of carbonyl (–CO) stretching frequency of the aldehyde (–CHO) group existing in the FP compound. 35 The FT-IR spectrum of BTA (Fig. 2b) shows a band between 3264 and 3350 cm −1 , correlated to the stretching frequencies of the –NH 2 and –NH moieties, and a prominent signal at 1640 cm −1 corresponding to the –CO of the amide group (–NH–CO).…”

Carbon quantum dots in bioimaging and biomedicines

“…Targeted delivery of medicinal medications loaded on CQDs, biological dye, and biological nanotransporters will become more and more significant. Enhanced photocatalytic antibacterial activity of covalent organic frameworks (COFs) is reported for CQDs as an electron extractant, which encompasses a great possibility for collaboration among material scientists and biochemical researchers for advanced biological and bio-environmental applications ( Das et al, 2022b ; 2023 ; Liang et al, 2022 ).…”

AgNPs Embedded in Porous Polymeric Framework: A Reusable Catalytic System for the Synthesis of α-Alkylidene Cyclic Carbonates and Oxazolidinones via Chemical Fixation of CO2

“…Therefore, nucleophilic attack on the center of carbon is quite vulnerable (e.g., when the DBU base activates the propargylic alcohol, the O atom may connect with the C center of CO 2 ), whereas electrophiles and the O center participate (e.g., activated alkyne moiety). In the potential intermediate, bond formation takes place between the Ag species and the alkyne component following a nucleophilic attack initiated by the oxygen center of CO 2 [87][88][89]. The adduct has been shown to be beneficial in the inclusion of CO 2 to produce the carbamate salt.…”
