Fernández Wang, Martí (Date of defense: 2017-07-20)
This doctoral thesis studies the involvement of challenging unsaturated substrates in the transition-metal catalysed [2+2+2] cycloaddition reaction, as well as new catalytic systems for the reaction. First, Morita-Baylis-Hillman ...
Vieta i Corcoy, Pep Anton (Date of defense: 2017-02-07)
Throughout this thesis I was involved in different science communication projects where research and innovation have been applied to improve existing proposals and exploring new formats without forget the evaluation of the ...
El Hamdi Lahfid, Majid (Date of defense: 2013-10-15)
Structural isomers are molecules that have the same number and type of atoms but arranged in different manner. The isomerization energy is the energy difference between two isomers, i.e. the energy cost corresponding to ...
Besalú Sala, Pau (Date of defense: 2024-05-20)
In this PhD thesis, we explore the fundamental properties of molecules and materials that shape their behavior and potential applications in science and technology. Specifically, we focus on developing advanced computer ...
Clarasó Petit, Carlota (Date of defense: 2019-02-08)
Metalloenzymes are a fundamental source of inspiration for synthetic chemists. Oxidation metalloenzymes catalyze oxidation reactions with high efficiency under very mild experimental conditions exhibiting exquisite regio- ...
Rovira Coll, Mireia (Date of defense: 2017-03-10)
Organometallic aryl-CuIII species have been proposed as key intermediates in Ullmann-type reactions. However, such species have long remained elusive and mechanistic investigations of a plausible catalytic cycle remained ...
Martínez López, Juan Pablo (Date of defense: 2016-11-18)
The physical and chemical properties of fullerenes and nanotubes can be conveniently tuned by the attachment of different functional groups to them. Therefore, the systematic understanding of different problems such as ...
Cassú Ponsatí, Daniel (Date of defense: 2018-04-20)
Transition metal-catalysed [2+2+2] cycloaddition reactions involving unsaturated substrates represent one of the most elegant methods in organic chemistry to prepare functionalised cyclic compound. This doctoral thesis is ...
Vila Vadrí, Jordi (Date of defense: 2023-04-21)
The development of novel catalytic methodologies involving the formation of carbon – carbon/heteroatom bonds to produce cyclic systems constitutes a field of great interest in the modern synthetic organic chemistry. Over ...
Horbatenko, Yevhen (Date of defense: 2013-12-13)
This thesis focuses on the study of hydrogen dynamic behavior in a series of proton sponge cations as well as in bis(silyl)hydride organometallic complexes. To understand the dynamic behavior, a new tool, i.e. the ...
García Borràs, Marc (Date of defense: 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 ...
Fuertes Espinosa, Carles (Date of defense: 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 (Date of defense: 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 ...
García Simón, Cristina (Date of defense: 2015-04-10)
Coordination-driven self-assembly has led to the realization of an increasing number of elegant and sophisticated functional structures, the structural complexity of which would be difficult to achieve using conventional ...
Acuña-Parés, Ferran (Date of defense: 2016-07-20)
One of the major current scientific goals is the development of renewable energy sources. An effective alternative to fossil fuels consists in the conversion of the sunlight energy into chemical fuels. The molecular hydrogen ...
