Reaction of Amino-Terminated PAMAM Dendrimers with Carbon Dioxide in Aqueous and Methanol Solutions

Publikováno v: Molecules, Vol 27, Iss 2, p 540 (2022)

Polyamines have been used as active materials to capture carbon dioxide gas based on its well-known reaction with amines to form carbamates. This work investigates the reactions between three amino-terminated poly(amidoamine) (PAMAM) dendrimers (G1,

Cathodic Voltammetric Behavior of Pillar[5]quinone in Nonaqueous Media. Symmetry Effects on the Electron Uptake Sequence

Autor: Angel E. Kaifer, Beijun Cheng

Publikováno v: Journal of the American Chemical Society. 137:9788-9791

The cathodic voltammetric behavior of pillar[5]quinone was investigated in dichloromethane solution. Our data show that the symmetry of the macrocycle has a pronounced effect on the electron uptake sequence. The uptake of the first five electrons fol

Rotaxane Formation by Cucurbit[7]uril in Water and DMSO Solutions

Autor: Sanem Senler, Angel E. Kaifer, Beijun Cheng

Publikováno v: Organic Letters. 16:5834-5837

The cucurbit[7]uril (CB7) host forms rotaxane-type complexes with dumbbell-shaped, cationic guests bis(3,5-dimethoxybenzyl)-4,4'-bipyridinium (1(2+)) and bis(3,5-diethoxybenzyl)-4,4'-bipyridinium (2(2+)). The kinetics of complex formation is slower w

Electrochemistry of viologen dications in cholate media and competition between the cholate assemblies and the cucurbit[7]uril host

Autor: Beijun Cheng, Angel E. Kaifer

Publikováno v: Langmuir : the ACS journal of surfaces and colloids. 31(10)

The cathodic voltammetric behavior of N,N'-dimethyl-4,4'-bipyridinium (methylviologen, MV(2+)), N,N'-dipropyl-4,4'-bipyridinium (propylviologen, PV(2+)), N,N'-dibutyl-4,4'-bipyridinium (butylviologen, BV(2+)), and N-heptyl-N'-ethyl-4,4'-bipyridinium
