摘要：

A self-assembling bis-pyrene (BP) molecule with pi-pi interactions was designed and synthesized. In condensed state, the BP self-assembled into highly-ordered mesophase at room temperature, which was characterized by using differential scanning calorimetry (DSC), polarized optical microscope (POM), and 1D wide angle X-ray diffraction (WAXD) techniques. In solution, the BP self-assembled into nanofibers in the mixed dichloromethane and hexane (1:1 volume ratio) solvent. Interestingly, the BP was not fluorescent when dissolved in dichloromethane solution. However, the self-assembled nanostructures of BP in the mixed solvent showed high intensity of green fluorescence. The advantages of self-assembly and fluorescence feature exhibited that BP could be promising fluorescence nanoprobes or nanosensors for various applications.
