Proposta de demarcação da estrutura supramolecular cristalina de sais de di-, tri- e tetrametilamônio
(Universidade Federal de Santa Maria, 2020-08-24)
Using the supramolecular cluster demarcation, whose criteria is the contact area between molecules, a series bromide salts of di-, tri- and tetramethylammonium was used as models to propose a demarcation of the supramolecular ...
Síntese e estudo supramolecular de bis-ureias trissubstituídas: mecanismos de cristalização
(Universidade Federal de Santa Maria, 2021-05-28)
This work presents the synthesis and molecular and supramolecular study of an unprecedented series of trisubstituted bis-ureas. In all, six molecules were synthesized, in which the substituents were varied and the methylene ...
Bis(alquilaril, aril)piridina-2,6-dicarboxiamidas: estrutura molecular, supramolecular e polimorfismo
(Universidade Federal de Santa Maria, 2020-03-02)
This work presents the study of intermolecular interactions and the molecular association process of bis (alkylaryl, aryl) pyridine-2,6-dicarboxamides, where the alkylaryl substitutes are (1) 2,2-diphenylethyl, (2) phenylethyl ...
[2]- e [3]rotaxanos como modelos para avaliar a influência das interações intercomponentes e intermoleculares no estado sólido cristalino
(Universidade Federal de Santa Maria, 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. ...
