Synthesis and optical properties of organic fluorescent nanowires and nanotubes.

The well controlled alpha,alpha'-bis(4-phenyl-1,3-butadienylidene)-acetone (BPBA) nanowires and nanotubes were prepared by a template wetting method. The diameter and length of BPBA nanowires and nanotubes were identical to template pores, diameter -80 nm and length -60 microm. This facile general approach can be used for the preparation of nanowires and nanotubes from common small organic molecules.
