文摘
The generation of long, mutually oriented nanofibers of functionalized phenylene oligomers is reported for the caseof symmetrically 4,4' ''-functionalized p-quaterphenylene molecules with chloride groups. Two domains of up to 30 
m long, orientedfibers with nanoscopic widths and heights grow along muscovite mica <110> directions. Their mutual alignment increases withincreasing substrate temperature during deposition. The photoluminescence spectrum around 380 nm shows well-resolved excitonictransitions and its overall intensity depends on fiber morphology.
