Stephan of the University of Toronto and his coworkers took the concept of Lewis acid-base pairs to a new level when they devised a chemical construct known as a frustrated Lewis pair. Lewis acid-base pairs are common in chemistry: An electron-deficient Lewis acid readily shares a Lewis ...
Frustrated Lewis Pairs.ppt,Frustrated Lewis Pairs 报告人:刘槟 2010年4月10日 FLPs的简介 Frustrated Lewis Pairs由Lewis acid和Lewis base组成,并且两种酸碱由于空间位阻原因而不能形成加成物。这种未能“淬灭”的酸碱能断开H2中的H-H键以及CO2中的C=O键,因此是一种
The concept of frustrated Lewis pairs (FLPs) has received considerable attention of late, and numerous reports have demonstrated the power of non- or weakly interacting Lewis acid–base pairs for the cooperative activation of small molecules. Although most studies have focused on the use of ...
In such systems,sterically hinderedLewis donors and acceptors are combined. Their steric demands preclude formation of simple Lewis acid-base adducts, allowing for the subsequent actions of both Lewis acids and bases on other molecules.This concept of FLPs has been extended to demonstrate new reactiv...
Lewis acid-base pairs are common in chemistry: An electron-deficient Lewis acid readily shares a Lewis base's spare electrons. However, when the Lewis acid and base each have bulky substituents, their ability to form a close relationship is denied, and the pair is said to become "frustrated...

Based on this meaning, we suggest a Chinese translation for this :frustrated Lewis pair, Lewis acid�base adduct, steric hindrance自Stephan等[1]2006年首次提出frustrated Lewis pairs(FLP)类物质用于可逆非金属催化加氢反应以来,该概念受到了国内外化学人士的广泛关注。Berke等[2]最近发表了一篇FLP活化端炔...
Besides the electronic structure and charge transfer efficiency, the enhanced Lewis acid–base pairs in amine-functionalized In2O3 are also expected to improve the adsorption and activation capacity for CO2. To investigate the CO2 uptake ability, we recorded the CO2 adsorption profiles on H-IO, Si...
BiOBr with surface frustrated Lewis pairs was synthesized by a simple chemical method.The CO evolution rate of CO2photoreduction for optimal Ti-BiOBr is 6.53 times higher than that of pristine BiOBr.The photocatalytic activity of Ti-BiOBr is improved due to the surface frustrated Lewis pairs.关键...
Subsequently, we show that by tuning the properties of the Lewis acid and base pair, the energy required for SET can be reduced to become thermally accessibledoi:10.1002/chem.202001494John Wiley & Sons, LtdChemistry – A European Journal
