title: Synthesis and optical properties of organic fluorescent nanowires and nanotubes.
abstract: 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. The forming of J-aggregates and the geometry of face to face overlap of the aromatic rings in BPBA nanowires and nanotubes resulted in clear bathochromic shifts of absorption peaks and fluorescence emission peaks compared with that of the monomer.
