We develop asymmetric synthetic methodologies applied to fullerenes and endofullerenes, enabling access to enantiomerically enriched carbon nanostructures. This research merges organic synthesis, catalysis and materials science to explore the unexplored stereochemical landscape of carbon allotropes.
We pursue the bottom-up and top-down synthesis of molecular nanographenes and carbon dots (CDs). Pulsed laser synthesis gives access to doped carbon nanoparticles of tailored composition, and liquid-phase exfoliation provides high-quality nanographene flakes. Carbon dots are synthesized from small organic molecules and functionalized for applications spanning optoelectronics, nanomedicine and antiviral materials.
We engineer multivalent glycofullerenes capable of blocking viral entry mediated by lectin receptors such as DC-SIGN, providing a scaffold-based antiviral strategy. Fluorescent BODIPY-conjugated derivatives enable mechanistic studies via single-particle tracking microscopy.
We develop new organic materials for next-generation solar cells, with a focus on perovskite-based devices. Our group synthesizes and evaluates hole-transporting and electron-accepting materials, studying the relationship between molecular structure and photovoltaic performance to advance the field toward efficient and long-term stable devices.
We design and synthesize organic molecules capable of efficient electroluminescence for application in OLED devices. Our focus is on Thermally Activated Delayed Fluorescence (TADF), a mechanism that allows triplet excitons — which account for 75% of electrically generated excited states — to be harvested via reverse intersystem crossing. This requires minimizing the singlet–triplet energy gap (ΔEST) through spatial segregation of HOMO and LUMO, achieved by combining electron donor and acceptor fragments.
We study the photophysical and photochemical behaviour of excited states in homogeneous and (micro/nano)heterogeneous media. Our research targets photoinduced energy and electron transfer processes underlying photocatalysis, photovoltaics, singlet oxygen photosensitization and photooxidation reactions, with applications spanning environmental remediation, antimicrobial photodynamic therapy and optical sensing.
On-surface synthesis under ultra-high vacuum (UHV) conditions allows us to build atomically precise graphene fragments and conjugated polymers directly on metallic substrates. By combining scanning probe microscopy with thermally controlled reactions, we achieve the bottom-up fabrication of covalent nanostructures with tailored electronic and topological properties, bridging molecular chemistry and surface science.

On 23 April 2026, the Universidad Complutense de Madrid honoured Dr. Laura Rodríguez Pérez (Faculty of Chemical Sciences) together with 123 other faculty members at a ceremony held in the Paraninfo Histórico de San Bernardo. The recognition is awarded under the Docentia-UCM evaluation programme, which incorporates feedback from students, peers and academic authorities — with student evaluations weighing two-thirds of the final score. This year, 31,885 students participated in the evaluation process.
Prof. Nazario Martín delivered a lecture at Fundación Ramón Areces commemorating the bicentennial of benzene's discovery by Michael Faraday in 1825. The talk traced the extraordinary journey of this deceptively simple molecule — from Faraday's isolation of 'bicarburet of hydrogen' from oil gas, through Kekulé's structural proposal, to its central role in modern organic chemistry, materials science, and the synthesis of molecular nanographenes. The event was attended by group members and prominent figures from the Spanish scientific community.
As part of its 40th anniversary celebrations, the University of Castilla-La Mancha unveiled a 'Muro de Vítores' — a gallery of 46 traditional academic emblems honouring all Doctores Honoris Causa, including Prof. Nazario Martín (DHC 2015).
