Supramolecular hydrogels of β-cyclodextrin linked to calcium homopoly-L-guluronate for release of coumarins with trypanocidal activity
(Elsevier, 2019)
Association constants and thermodynamicsparameters on inclusion of four 3-amido coumarins that present trypanocidal activity, into 6-amino-beta-cyclodextrin (1: 1 stoichimetry) were determined. In addition, pure ...
Estudo e caracterização físico-química de sistemas supramoleculares nanoagregados e de matrizes poliméricas associadas à ciclodextrina
(Universidade Federal de Minas GeraisUFMG, 2010-12-15)
Herein, supramolecular systems involving beta-cyclodextrin and polymer matrix were prepared and characterized. More specifically, the host-guest system formed between beta-cyclodextrin and BPP10c, a bradykinin potentiating ...
Kinetic parameters for thermal decomposition of supramolecular polymers derived from diclofenac-meglumine supramolecular adducts
(2013-01-25)
Meglumine is an aminocarbohydrate able to form supramolecular adducts with organic acids. The recognition is based on hydrogen bonds and the structures resulting from the complexation have high solubility in water. This ...

Versatile Supramolecular Organogel with Outstanding Stability toward Aqueous Interfaces
(American Chemical Society, 2014-06)
In this communication we report on a novel and versatile low molecular weight organogelator. The methanolic gel exhibits an exceptional water-enhanced stability as evidenced by a 30oC increase in Tg with up to 10 %v/v of ...
Self-Sustaining Supramolecular Ionic Liquid Gels for Dye Adsorption
(2018)
Water contamination is one of the main problems ofmodern society, and scientific research is continuously involved in identifying solutions able to preserve this valuable source. In this context, we characterized novel ...
Nickel(II) complexes based on L-amino-acid-derived ligands: Synthesis, characterization and study of the role of the supramolecular structure in carbon dioxide capture
(International Union of Crystallography, 2020-09)
The formation of the symmetrical 3-carbonate-bridged self-assembled trinuclear NiII complex Na2{[Ni(LO)2(H2O)]3(3-CO3)} (LO is the carboxylate anion of a l-tyrosine derivative), involves atmospheric CO2 uptake. The asymmetric ...
Efeitos energéticos e topológicos no design de cocristais de compostos aromáticos e em 1,5-diaril-1h-pirazol-3-carboxilatos de etila
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2017-07-20)
This work presents the study of the supramolecular environment in multicomponent crystals. Multicomponent
crystals were defined by J. D. Dunitz as a crystal containing two or more components together, so that this
concept ...
Supramolecular organization-electrical properties relation in nanometric organic films
(Amer Chemical Soc, 2015-05-28)
The need to improve the performance of electronic devices based on organic materials has been at the center of Structure property relation research, where the main objective is to develop low cost and flexible electronic ...
