For the selective separation of Noble Metals, different new chelating polymers with the same functional group, based on tri-isobutylphosphine sulphide, have been synthesised. Different spacers between the polymeric matrix ...
Borrell Recasens, Margarida (Data de defensa: 2021-11-05)
Oxidations are an important kind of reactions which are traditionally performed using stoichiometric oxidants that generate a large amount of waste. Syn-dihydroxylation of alkenes is a paradigmatic example because it is ...
Ng Choi, I-teng Montserrat (Data de defensa: 2015-12-15)
The incorporation of unsymmetrical biaryl systems into peptide sequences is a strategy that can improve their biological activity. Due to the difficulty of arylating the 4(5}-position of the imidazole ring, this doctoral ...
Rosés Subirós, Cristina (Data de defensa: 2016-01-22)
This thesis is focused on the development of synthetic approaches to obtain new bioactive peptides. The first part deals with the design of new antimicrobial peptide/cell-penetrating peptide conjugates as anticancer agents. ...
García Borràs, Marc (Data de defensa: 2015-05-29)
It all started in 1985, when Kroto, Smalley and Curl discovered by serendipity a new carbon allotrope. They synthesized for the first time the C60 molecule, and named it as ”Buckminsterfullerene”, because of the similarity ...
Fontanet Cepeda, Mònica (Data de defensa: 2013-11-22)
In this thesis is presented the synthesis and characterization of two different carboranylcarboxylate ligands, 1-CH3-2-CO2H-1,2-closo-C2B10H10 and 1-CO2H-1,2-closo-C2B10H11, in which the methyl group bonded to the carbon ...
Fuertes Espinosa, Carles (Data de defensa: 2020-07-23)
The use of self-assembly to bring simple building blocks together into complex product, has led to the preparation of an increasing number of sophisticated and functional 3D supramolecular nanocapsules. By understanding ...
Ubasart Clarà, Ernest (Data de defensa: 2022-10-28)
The development of supramolecular assemblies with big cavities is important to recognize specific guests or infer a chemo- or regioselective chemistry, in analogy to natural enzymes. The objective of this thesis was to ...
