Supramolecular Organometallic and Main Group Chemistry Laboratory

Research Interests

Welcome to our Research Group. We are a highly motivated team working towards two main research streams. On one side, the development and understanding of the chemistry of confined supramolecular organometallic systems, and on the other side, the study of low-valent main group organometallics systems’ reactivity and their bonding to transition metals. Both research avenues respond to the same call, finding molecular and supramolecular catalytic systems to activate “inert” molecules. In particular, the activation of CO2 is of interest to this research team because of its environmental implications to the chemical and energy industries in developing a sustainable way to transform energy with cero carbon emissions.The control of reactivity, selectivity, and stability at an active catalytic site is often achieved by tuning the catalytic metal first coordination sphere. However, an alternative and powerful way to make a better stereo-control is tailoring the secondary coordination sphere by employing well-defined and discrete host cavities as reaction nanovessels.The encapsulation of organometallic catalytic systems allows access to unique reaction microenvironments that drastically influence the course of catalytic reactions, in a way that the non-encapsulated free catalyst can outcompete. Both the catalyst and host cavity control the catalytic properties of the confined system. This dual-manifold allows fine-tuning for kinetic stabilisation, creating a unique confined chemical space and giving access to better catalyst stability, novel selectivity, and accelerating the reaction rate. Many of these catalyst features remark their relevance to the operation of enzymatic catalysis.


Our motivation is to use our findings in confined and main group chemistry to advance chemical research and catalysis while promoting sustainability.

Biographical Sketch

Dr Martínez was born in Murcia, Spain, in 1981. He completed the BSc degree in Chemistry at the University of Murcia in 2015, where he also did his PhD supervised by Prof José Vicente and M. T. Chicote in organopalladium chemistry in 2012. During this period, he also worked with Prof John McGrady at the University of Glasgow (UK) studying computational organometallic chemistry. From 2012–2016, he worked with Dr Charles O’Hara and Prof Robert Mulvey at the University of Strathclyde (UK) in template main group supramolecular chemistry, and the synergistic co-operation effects in bimetallic main group systems to influence the regio-selectivity of organic reactions. From 2017–2019, worked at the University of Oxford in solid-gas catalysis using the encapsulation of transition metal catalysts in non-covalent organometallic frameworks towards the valorisation of light hydrocarbons with Prof Andrew Weller, in partnership with SCG Chemicals Ltd, one of the largest integrated petrochemical industries in Asia.

He initiated independent research as a Ramón y Cajal Researcher at the University of Huelva and the Research Center CIQSO in 2019, and currently, he is leading a young and dynamic research group.
