Beyond shifting the absorption spectrum, nitrogen doping can also enhance the photochemical stability and charge transport properties of organic materials. Nitrogen atoms can introduce additional electron-donating or electron-withdrawing effects depending on their local environment, which can impact the photophysical behavior and electronic structure of the material . For example, in conjugated organic systems, nitrogen doping can increase the delocalization of charge carriers, facilitating charge separation and reducing recombination, which is particularly beneficial for photocatalytic applications. Additionally, nitrogen-doped organic materials often exhibit improved fluorescence properties , as the doping can fine-tune the molecular orbitals and enhance radiative recombination rates. These modifications make nitrogen-doped organic molecules highly attractive for solar energy conversion, organic light-emitting diodes (OLEDs), and other optoelectronic devices, where efficient light absorption, charge separation, and emission are crucial for performance.
