790 nm, 830 nm). The fluorescence spectrum after continuous-wave (CW) UV excitation is shown for comparison. 

The nonsymmetrically functionalized p-quaterphenylenes, however, behave differently [135]. 

For the observation of the fibers intrinsic properties, nanofibers obtained from MONHP4 and MOCLP4 have been transferred from mica to glass (silicon oxide) using a standard procedure [17, 18] in order to avoid second-harmonic generation from the underlying substrate and a wetting layer. 

To return to the initial question Is the combination of p-hexaphenylene as a molecular building block and muscovite mica as a growth substrate truly unique for generating nanofibers No, it is not. In chapter the following results have been presented  

it is possible to obtain tailored nanofibers from appropriately functionalized p-quaterphenylenes. A requirement for generating aligned nanofibers still seems to be muscovite mica as growth substrate, but the molecular basis is not restricted to p6P a para-phenylene molecular basis can be employed which tolerates functional groups at the para-positions.
