A general
and efficient C(α)-alkylation of oxindoles with
unactivated secondary alcohols as alkylating agents catalyzed by a
newly developed NNN-Mn(II) complex is reported. Mechanistic studies
illustrate that the importance of the NH moiety in the complex and
M–L cooperation play very important roles during the catalytic
transformation.
Simple donor-acceptor derivatives have been prepared by substituting alicylic amines into 2,2'-bipyridine (Bpy) core unit that exhibited substituents structure dependent solution and solid state fluorescence, solvatochromism, halochromic fluorescence switching in...
A series of stimuli-responsive AIEgens of tetraphenylethyelene (TPE) fused Imidazole derivatives (1-7) were synthesized and explored their substituents controlled fluorescent properties in the solid state. The structure of the synthesized...
Hydrazone photoswitching functionality integrated with three different fluorophore units (perylene (PY-PH), tetraphenylethylene (TPE-PH) and triphenylamine (TPA-PH)) were synthesized and demonstrated fluorophore unit dependent fluorescence photoswitching and mechanofluorochromism. TPE-PH and TPA-PH...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
