We were honoured to host the V Autumn Meeting of the Polish Photochemistry Group, also known as ‘Molecules & Light.‘ This gathering, organized by the Polish section of the EPA, aimed to bring together researchers in the fields of photophysics, photochemistry, photocatalysis, and molecular spectroscopy. The event welcomed 86 participants, not only from Poland but also from countries including the USA, Germany, Italy, the Czech Republic, Slovakia, and Saudi Arabia. Throughout the meeting, we had the privilege of enjoying six outstanding plenary lectures, 39 inspiring oral presentations, and 37 impressive poster presentations.
