Paper Abstract

Nanofibers from symmetrically and unsymmetrically functionalized p-quaterphenylenes are fabricated by a bottom-up process on muscovite mica. The symmetrically functionalized p-quaterphenylenes emit intense, polarized blue light after unpolarized UV-excitation. Upon implementing electron push-pull functional groups like chlor and methoxy groups to the molecular building block new properties of the nanoaggregates have been generated: the nanofibers exhibit increased non-linear optical properties, acting, e.g., as frequency doublers after excitation with NIR femtosecond laser pulses. Depending on the growth conditions the chloro-methoxy-p-quaterphenylene forms either parallel nanofibers or nano-branches on a muscovite mica substrate, adding another degree of freedom for the design of, e.g., resonator structures.
