description Unveiling the mechanisms behind light-matter interactions is of great interest to find different ways to convert and control light energy. This thesis falls on the photophysics field, the objective is to study how different molecular materials, with different photophysical properties, behave when they are photoexcited without modifying its chemical composition. By this, a characterization of its electronic properties in the excited states can be performed, allowing the possibility to identify possible applications that can be addressed to obtain benefits from them, for instance applications such as dye sensitized solar cells, catalytic systems, light emitting diodes or laser active media. The materials this thesis focuses on are nanographene-based molecules. These materials can be conceived as small patches of the graphene mesh. But, unlike graphene, they present a gap as a consequence of their quantum confinement, which can be tuned by varying the shape and type of edges or their length, allowing them to be used as chemically tuneable semiconductors.
