Cochineal quinone carbon dot synthesis via a keto–enol tautomerism strategy and their intermolecular photo-induced cross-redox interactions with tetracycline

Abstract

Natural products originated carbon dots promising a charming and valuable platform for bio-fluorescence probes, however, application scope of these probes was seriously restricted, due to the indistinct molecular structures of...

Electrocatalytic synthesis of α,α-gem-dihalide ketones from α-mono-halide ketones and unexpected dimer condensation

“…Next, radical inhibition experiments were conducted in the presence of a stable oxyl-radical, 2,2,6,6-tetra-methyl-1-oxylpi-peridine (TEMPO) (Scheme 4D). 44 The results of these experiments showed that the electrocatalytic halogenation and dimer condensation processes were inhibited, indicating that a halogen radical was involved in the electro-halogenation. In contrast, dimer condensation occurred via electrocatalysis rather than a Lewis base-induced haloform reaction.…”

Photocatalytic [4+2] cyclization of biomass furan into a cantharidin-like skeleton

“…The Stern-Volmer plot was collected from furan solutions consisting of furan + maleic anhydride + O 2 , and furan + O 2 mixture (see details in ESI †). 42 The UV-VIS and fluorescent spectra of Ru(bpy) 3 Cl 2 were recorded. Ru(bpy) 3 Cl 2 showed an optical absorption maximum at 300 nm under the excitation wavelengths of 300 nm, and it showed an emission peak at l em = 320 nm.…”

Recent progress of carbon dot fluorescent probes for tetracycline detection

“…Nevertheless, the strong acids in the CDs are not conducive to separation and inevitably affect the environment. 30…”
