Resumen
Los investigadores aprovecharon los enlaces de calcógeno (Te·O o Se·O) para crear nuevos supraanfífilos. Estas moléculas se autoensamblan en vesículas supramoleculares y nanofibras, ofreciendo nuevas posibilidades en la química supramolecular.
Área de la Ciencia:
- Química supramolecular
- Ciencias de los materiales
- Física y Química
Sus antecedentes:
- El enlace de calcógeno es una interacción no covalente emergente.
- El aprovechamiento de los enlaces de calcógeno para el autoensamblaje molecular sigue siendo en gran medida inexplorado.
Objetivo del estudio:
- Para reportar el primer caso de supra-anfifilos impulsados por la unión de calcógeno.
- Para investigar el auto-ensamblaje de estas nuevas moléculas en nanoestructuras.
Principales métodos:
- Diseño de un donante macrocíclico de casi calix[4]calcogenadiazol (C4Ch).
- Diseño de un surfactante de óxido de piridina con cola como aceptor molecular.
- Formación de complejos donante-receptor a través de enlaces de calcógeno Te·O o Se·O.
Principales resultados:
- Formación exitosa de nuevas supraanfifilas a través de interacciones de enlace de calcógeno.
- Demostración de autoensamblaje en vesículas y nanofibras supramoleculares.
- Control sobre la geometría de la nanoestructura dictada por la afinidad de los enlaces de calcógeno.

31.5K
Stable molecules exist because covalent bonds hold the atoms together. The strength of a covalent bond is measured by the energy required to break it, that is, the energy necessary to separate the bonded atoms. Separating any pair of bonded atoms requires energy — the stronger a bond, the greater the energy required to break it.

02:43Peptide Bonds
83.4K
A peptide bond covalently attaches amino acids through a dehydration reaction. One amino acid's carboxyl group and another amino acid's amino group combine, releasing a water molecule. The resulting bond is the peptide bond. The products that such linkages form are peptides. As more amino acids join this growing chain, the resulting chain is a polypeptide. Each polypeptide has a free amino group at one end. This end has the N-terminal, or the amino-terminal, and the other end has a free...

Overview
When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.

Chemical bonding theories were pioneered by American chemist Gilbert N. Lewis. He developed a model called the Lewis model to explain the type and formation of different bonds. Chemical bonding is central to chemistry; it explains how atoms or ions bond together to form molecules. It explains why some bonds are strong and others are weak, or why one carbon bonds with two oxygens and not three; why water is H2O and not H4O.
