Prof. LOPPACHER Christian, IM2NP - Université Aix-Marseille (rapporteur) Prof. RICHTER Christine, DICO - CY Cergy Paris Université (rapportrice) DR CNRS BORISSOV Andrey, ISMO - Université Paris Saclay (rapporteur) Prof. MASSON Laurence, CINAM - Université Aix-Marseille (examinatrice) DR CEA FIORINI Céline , SPEC – IRAMIS - CEA Saclay (examinatrice) DR CNRS CLAIR Sylvain, IM2NP - Université Aix-Marseille (examinateur) DR CNR DELERUE Christophe, IEMN - Université de Lille (garant). This HDR memoir presents a concise overview of my research activity, from postgraduate studies to my current academic position, with a focus on nanoscience, surface science, and materials science. It begins with the scientific motivations behind the choice of these fields, followed by a summary of the work carried out during successive postdoctoral appointments. These studies primarily address the controlled growth of two-dimensional (2D) organic and inorganic films, as well as one-dimensional (1D) and zero-dimensional (0D) nanostructures, investigated using a broad range of advanced surface-sensitive techniques.These projects laid the conceptual and methodological foundation for my current research and directly inspired its development. My ongoing work builds on the expertise acquired and aims to address long-term goals in the design of adaptive polymers and nanostructured graphenes as versatile platforms for engineering robust 2D layers with tunable, integrated functionalities. The approach involves designing specific functional units at the molecular level and scaling them up through integration into extended 1D and 2D polymeric or graphenic architectures. A central aim of my current projects is to establish precise control over the shape, dimensionality, chirality, and functionality of the resulting nanostructures, and to enable their effective transfer onto targeted substrates for further integration into van der Waals heterostructures and prototypal devices. With this objective, four main research directions have been initiated and are currently in progress: (i) investigating the role of triphenylamine functionalization on the formation of surface-confined organic frameworks (SCOFs); (ii) engineering and probing the physical properties of novel nanoporous graphene structures; (iii) fabricating and studying nanostructured carbon nitrides; and (iv) examining the influence of substrate type on the growth of molecular switch films, with the goal of achieving controllable tuning of properties in the resulting 2D materials. .
