Low molecular weight gelators (LMWG) have been extensively explored in many research fields due to their unique reversible gel–sol transformation. Intermolecular interactions between LMWG are known as the main driving force for self-assembly. During this self-assembly process, individually analyzing contribution difference various intermolecular is crucial understand gel properties. Herein, we report 2,5-bis(hexadecylcarbamoyl)terephthalic acid (BHTA) a LMWG, which could efficiently form...
Surfactants are widely used in fields such as oil recovery and flotation. The properties mechanisms of surfactants can be effectively studied using molecular dynamics (MD) simulations. Herein, the aggregation behavior was at oil–water interface by MD simulation, micro-morphology analyzed under a low concentration saturated state interface, respectively. visualization results simulation showed that DTOA 120 surfactant molecules, whereas 160 molecules were required for BEMA. In addition,...
An aerobic oxidative cyanation for the synthesis of α-aminonitriles was reported. The formation C(sp3)-CN bonds achieved under a metal-free condition by utilizing azobis(isobutyronitrile) as sole organic cyanide source with combination pivalic acid and sodium acetate additives.

A series of phthalic acid derivatives (P) with a carbon-chain tail was designed and synthesized as single-component gelators. combination the gelator P non-gelling additive n-alkylamine through acid–base interaction brought about novel phase-selective two-component gelators PA. The gelation capabilities PA, structural, morphological, thermo-dynamic rheological properties corresponding gels were investigated. molecular dynamics simulation showed that H-bonding network in PA formed between NH...
Although direct acetoxylation and cyclization of alkylamide have been extensively reported, investigation the structural influence directing groups on selectivity is limited. Pd-catalyzed 2-methoxyiminoacyl (MIA) assisted γ-acetoxylation alkylamides has developed. Further DFT studies demonstrated that a significant reductive elimination step. The strong electron-donating effect OMe group in MIA leads to preferential formation five-membered cyclopalladium (OAc-Pd-C) complex, which favors pathway.
A new concept of a cluster frustrated Lewis pair (CFLP) featuring extensive cooperative effects both within acidic/basic components and between partners has been proposed.
