Used as a fluorescent probe in biochemical and biophysical research due to its ability to undergo photoisomerization and emit light upon excitation. It is employed in studies of membrane dynamics, protein interactions, and molecular conformation changes. Its rigid, conjugated structure makes it suitable for investigating energy transfer processes and as a model compound in photophysical studies. Also utilized in organic electronics and as a building block in the synthesis of more complex conjugated systems for optoelectronic applications.
