| Sumario: | A set of novel Donor-Acceptor-Donor (D-A-D) benzoselenadiazole derivatives has beensynthesized and crystallized in nanocrystals in order to explore the correlation between their chemicalstructure and the waveguided luminescent properties. The findings reveal that all crystals exhibitluminescence and active optical waveguiding, demonstrating the ability to adjust their luminescencewithin a broad spectral range of 550–700 nm depending on the donor group attached tothe benzoselenadiazole core. Notably, a clear relationship exists between the HOMO-LUMO energygaps of each compound and the color emission of the corresponding optical waveguides. Theseoutcomes affirm the feasibility of modifying the color emission of organic waveguides through suitablechemical functionalization. Importantly, this study marks the first utilization of benzoseleniadiazolederivatives for such purposes, underscoring the originality of this research. In addition, theobtention of nanocrystals is a key tool for the implementation of miniaturized photonic devices. |
