Mariana Silva Faria Peixoto is a PhD student in Chemistry at the University of Coimbra, specializing in sustainable organic synthesis, mechanochemistry, and the photophysical characterization of functional organic molecules. She holds a BSc in Medicinal Chemistry and an MSc in Chemistry (Advanced and Industrial Chemistry: Development and Strategy) from the same institution. Her research has focused on the development of greener synthetic methodologies, including solvent-free and mechanochemical approaches, and the evaluation of sustainability using quantitative green chemistry metrics. During her MSc, under the supervision of Prof. Marta Piñeiro, she worked on adapting conventional synthetic routes to more sustainable alternatives for porphyrin derivatives. This work resulted in three peer-reviewed publications in Molecules, Green Chemistry Letters and Reviews, and the Journal of Porphyrins and Phthalocyanines. She later joined the SunStorage project as a research fellow, contributing to the synthesis and characterization of functional porphyrin systems for solar energy applications. Since 2021, her research has focused on the design, synthesis, and photophysical characterization of aggregation-induced emission luminogens (AIEgens), in collaboration with Prof. J. Sérgio Seixas de Melo and international partners. This work has contributed to several peer-reviewed publications, including a communication in Chemistry – A European Journal. Her work integrates synthetic design, reaction optimization, and sustainability assessment, with particular emphasis on the development of efficient and environmentally responsible synthetic methodologies. She is currently developing mechanochemical strategies and sustainable synthetic methodologies for functional organic molecules.
