Abstract :

Solid state lighting (SSL) of organic chromophores has attracted much attention due to their potential applications in devices such as light-emitting diodes, photovoltaic devices and sensors. Tuning and controlling the wavelength of emission of an organic material is crucial to identify the appropriate application and the optical properties of different dyes in the solid state and strongly depend on the molecular structure and intermolecular interactions. Recently, organic chromophores that exhibit quenching of fluorescence in the solid state have been reported and this phenomenon is termed as aggregation caused quenching (ACQ). Herein, we report results from optical characterization (absorption and emission) of α, β-unsaturated acrylonitrile with structures of electron donor D-𝜋-A acrylonitrile derivatives. The investigation reveals differences in the characteristic emission such as an enhancement in fluorescence in solvent, as well as in the solid state. Their photophysical properties have been investigated to evaluate the effect of the substituents, which afforded a dye that exhibited emission depending of the morphology.
