Aminoboranes as modulable platforms for developing efficient fluorophores and EnT photocatalysts

Aryl aminoboranes, distinguished by their boron-nitrogen bond, are a versatile class of compounds with broad applications in organic and materials chemistry. This thesis investigates their synthesis, photophysical properties, and synthetic utility. In chapter 5, exploration around this molecular scaffold established aryl aminoboranes as photo-organocatalysts for visible light-mediated energy transfer (EnT) reactions, advancing sustainable catalysis. These findings underscore the transformative potential of aryl aminoboranes in materials chemistry, molecular synthesis and photocatalysis. In chapter 6 a photoluminescent study of a sub-class of aryl aminoboranes demonstrated their efficacy as fluorescent co polymers in 3D-printed resins. In chapter 7, collaborative research with Dr. Malik and Prof. Melchiorre exploring 4-hydroxycoumarin derivatives for photo-reductions and EnT is presented, further expanding the organic chemist toolbox with cheap photo-organocatalysts applicable in different fields of catalysis. Finally, in chapter 8 a study with Dr. Pecchini, Dr. Santarelli, and Prof. Bernardi delineated the scope and mechanism of a novel tricomponent reaction involving sulfoxonium ylides.
