Solid-state emissive small molecules comprising 1,2,4-oxadiazole scaffold: intramolecular charge transfer-driven tunable photophysical properties

Key Points

• Tunable photophysical properties were achieved through intramolecular charge transfer mechanisms in solid-state emissive small molecules.
• Significant emission shifts were observed, with a maximum emission wavelength change of up to 100 nm.
• Characterization of these compounds was conducted using UV-Vis spectroscopy and photoluminescence analyses.
• These findings may enable development of advanced materials for optoelectronic devices and sensors.
