Andrea Lapini received the master degree in Chemistry in 2005 from the University of Florence (110/110) and the PhD In Chemical Science from the Science Doctorate School of the University of Florence and the European Laboratory for Non-Linear Spectroscopy (LENS). During the PhD he developed a pronounced interest towards the usage of Coherent Ultrafast Spectroscopy to disentangle electronic and structural properties of simple and complex molecular systems. He spent the years between 2009 and 2017 as a pots-doctoral fellow @ LENS developing most of instrumentation nowadays employed to performed 2DIR and 2D-Visible spectroscopy. In 2018 Andrea got a permanent position as a researcher in the National Institute of Metrological Research (INRIM) in Turin, within the Advanced Material and Life Science division. In 2021 Andrea got a position as a Tenure-track Assistant Professor in Physical Chemistry at the Department of Chemistry, Life Science and Environmental Sustainability in Parma.

Geometry Controls Confined Water Dynamics in Lipidic Mesophases Sara Catalini, Matteo Rutsch, Andrea Lapini, Barbara Rossi, Mariangela Di Donato, et al. Angewandte Chemie International Edition, 2026 Water under nanoscale confinement is central to biological function, catalysis, and soft materials, yet how geometry dictates its structure and dynamics remains unresolved. Here, we establish a direct link between interfacial curvature and confined water behavior using an archaeal‐inspired phytantriol‐water lipidic mesophase platform. By systematically tuning curvature across lamellar, double‐gyroid cubic, and reverse micellar phases, and integrating structural, thermodynamic, and ultrafast spectroscopies, we show that geometry controls the dimensionality and mobility of the hydrogen‐bond network. Planar interfaces enforce 2D networks that slow down interfacial water through spatial constrain, whereas curved bicontinuous and micellar topologies promote 3D networks with accelerated reorientation. These findings reveal a geometric principle for governing water dynamics in soft nanoconfinement, providing molecular level design rules for confined transport and reactivity in membranes and functional materials.
Supramolecular topological adhesion boosts delamination resistance in carbon fiber reinforced polymers Monica Milani, Silvia D’Auria, Francesco Bertocchi, Alice Boschetti, Andrea Lapini, et al. Advanced Composites and Hybrid Materials, 2026 In this study, we introduce supramolecular topological adhesion as an innovative and effective methodology to enhance interlaminar fracture toughness in carbon fiber reinforced polymers (CFRPs). We achieved remarkable improvements in delamination resistance by physically entangling phenoxy resins within an epoxy matrix and introducing sacrificial H-bond interactions via ODIN (1-(7-Oxo-7,8-Dihydro-1,8-Naphthyridin-2-yl)urea) units. The ODIN units form sextuple H-bonding dimers in the cured epoxy matrix among plies, experimentally quantified via UV–Vis spectroscopy, whose detachment hinders crack propagation. The viability of this approach was tested using various phenoxy resins with different molecular weights and with different levels of ODIN functionalization. Single lap shear (SLS) tests demonstrated a notable increase in adhesion strength, pointing out PKHB-ODIN 13% as the best candidate as interlaminar adherent. Delamination resistance was determined through double cantilever beam (DCB) and end-notched flexure (ENF) tests, showing up to 120% and 80% increases in Mode I and Mode II fracture toughness, respectively. The limited DCB and ENF test increments observed for control adherent PKHB-PU 23% functionalized with phenylurea (PU) groups, demonstrates that the strength of topological H-bonding is pivotal to boost delamination resistance. The results indicate that this method holds great potential for improving the durability of CFRP composites, especially in applications requiring high resistance to delamination.
How the nitro group position determines the emission properties of π-expanded diketopyrrolopyrroles Kamil Skonieczny, Francesco Di Maiolo, Sara Venturi, Alessandro Iagatti, Alessandro Ricci, et al. Physical Chemistry Chemical Physics, 2025 When the nitro group is located at a distant position with respect to the lactam moiety, the expanded DPP exhibits strong emission with optical brightness exceeding 110 000 (M−1 cm−1) in non-polar solvents.
Nanothermometer Based on Polychlorinated Trityl Radicals Showing Two-Photon Excitation and Emission in the Biological Transparency Window: Temperature Monitoring of Biological Tissues Nerea Gonzalez‐Pato, Davide Blasi, Domna M. Nikolaidou, Francesco Bertocchi, Jesús Cerdá, et al. Small Methods, 2024 Nanothermometers are emerging probes as biomedical diagnostic tools. Especially appealing are nanoprobes using NIR light in the range of biological transparency window (BTW) since they have the advantages of a deeper penetration into biological tissues, better contrast, reduced phototoxicity and photobleaching. This article reports the preparation and characterization of organic nanoparticles (ONPs) doped with two polychlorinated trityl radicals (TTM and PTM), as well as studies of their electronic and optical properties. Such ONPs having inside isolated radical molecules and dimeric excimers, can be two‐photon excited showing optimal properties for temperature sensing. Remarkably, in TTM‐based ONPs the emission intensity of the isolated radical species is unaltered increasing temperature, while the excimer emission intensity decreases strongly being thereby able to monitor temperature changes with an excellent thermal absolute sensitivity of 0.6–3.7% K−1 in the temperature range of 278–328 K. The temperature dependence of the excimeric bands of ONPs are theoretically simulated by using electronic structure calculations and a vibronic Hamiltonian model. Finally, TTM‐doped ONPs as ratiometric NIR‐nanothermometers are tested with two‐photon excitationwith enucleated pig eye sclera, as a real tissue model, obtaining a similar temperature sensitivity as in aqueous suspensions, demonstrating their potential as NIR nanothermometers for bio applications.
Tuning the Optical Properties Through Hydrogen Bond-assisted H-aggregate Formation: The ODIN Case Francesco Bertocchi, Danilo Marchetti, Sandra Doria, Mariangela di Donato, Cristina Sissa, et al. Chemistry A European Journal, 2024 The current work focuses on the investigation of two functionalized naphthyridine derivatives, namely ODIN‐EtPh and ODIN‐But, to gain insights into the hydrogen bond‐assisted H‐aggregate formation and its impact on the optical properties of ODIN molecules. By employing a combination of X‐ray and electron crystallography, absorption and emission spectroscopy, time resolved fluorescence and ultrafast pump‐probe spectroscopy (visible and infrared) we unravel the correlation between the structure and light‐matter response, with a particular emphasis on the influence of the polarity of the surrounding environment. Our experimental results and simulations confirm that in polar and good hydrogen‐bond acceptor solvents (DMSO), the formation of dimers for ODIN derivatives is strongly inhibited. The presence of a phenyl group linked to the ureidic unit favors the folding of ODIN derivatives (forming an intramolecular hydrogen bond) leading to the stabilization of a charge‐transfer excited state which almost completely quenches its fluorescence emission. In solvents with a poor aptitude for forming hydrogen bonds, the formation of dimers is favored and gives rise to H aggregates, with a consequent considerable reduction in the fluorescence emission. The urea‐bound phenyl group furtherly stabilizes the dimers in chloroform.
