Rotâmeros de [2]rotaxanos: estudo do efeito do macrociclo sobre o eixo molecular
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2017-07-20)
This work presents the synthesis of three new threads and three new [2]rotaxanes models that have asymmetric stopprs, which allows rotamers to be obtained. The synthesis of the [2]rotaxanes was performed by clipping reaction, ...
[2]- e [3]rotaxanos como modelos para avaliar a influência das interações intercomponentes e intermoleculares no estado sólido cristalino
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2021-07-30)
Rotaxanes are widely studied for their ability to move one component relative to another. Intercomponent interactions are widely studied in solution and have been gaining more field in the crystalline solid state. ...
Síntese e caracterização de [2]rotaxano: estudo conformacional em solução
(Universidade Federal de Santa MariaBrasilUFSMCentro de Ciências Naturais e Exatas, 2019-11-25)
Rotaxanes molecules became an important model for studying supramolecular chemistry by theirs unique motions and characteristics. In this context, this work was based in the synthesis of three molecules. One secondary ...
Síntese e caracterização de [2]rotaxanos: uso de eixos moleculares com estações succinamida e oxoalquil-triazol
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2022-03-04)
The following work presents the synthesis of molecular thread and molecules of rotaxanes containing two stations, succinamide and oxoalkyl-triazole. The synthetic process of the molecular thread was carried out by “click” ...
Influence of axle length on the rate and mechanism of shuttling in rigid H-shaped [2]rotaxanes
(Royal Society of Chemistry, 2017)
Preparación de un plausible eje de rotaxano quiral aminoácido-esteroide
(Universidad Autónoma Metropolitana (México). Unidad Azcapotzalco. División de Ciencias Básicas e Ingeniería., 2021)
Rotaxanes are compounds that are made up of two submolecular components: a cyclic one (a ring) and a linear one (an axis) that threads the previous one and that, in addition, has bulky groups at their ends in order to keep ...
