Abstract
A handful of cyano-stilbene derivatives are successfully synthesized through Williamson and Suzuki reaction. The dipole-dipole interaction of intramolecular charge-transfer molecule is used to self-assembly microstructure of the as-prepared materials. The CNS-1 microstructures are large-scale spherical particles. However, compound CNS-2 forms straight one-dimensional (1-D) microribbons. Additionally, the morphology of micro-structures obtained from compounds CNS-3 and CNS-5 are large-scale spheres with several micrometres.
