Abstract [eng] In this PhD dissertation, the tuning of intramolecular and intermolecular charge transfer emissions in novel organic materials is examined, with a focus on their potential applications in electroluminescent devices and sensing. The study investigates the optoelectronic, photophysical, and electrochemical characteristics of substances displaying thermally activated delayed fluorescence (TADF). A major field of interest is how organic semiconductors react to outside stimuli such as temperature and UV radiation, which affects their emissive behaviour, molecules conformation, and morphology. The study highlights the significance of novel phenomena for optoelectronic applications, such as thermally controlled mechanochromic luminescence and photostimulated fluorescence. A number of recently created organic compounds are examined for their structural and functional characteristics. The study offers significant insights into material design by exposing charge transfer pathways and their role in improving emission efficiency. The knowledge of organic semiconductors and their promise for high-performance, sustainable devices like OLEDs and UV sensors is greatly expanded by this work. It lays the groundwork for the creation of next-generation materials for optoelectronic devices by revealing how external stimuli can be used to control molecular characteristics.
