Di-functionalized p-Quaterphenylenes

The whole variety of nanoaggregates shown so far was generated from comparatively simple, symmetrically functionalized oligomers, but nonsymmetrically functionalized oligomers also self-assemble into well-shaped nanostructures. 

Vapor deposition of MOCLP4 results in well-defined nanostructures [128] that show a strong dependence on the growth temperature clearly a high surface 

Ts = 360 K, 5 nm, and (c) high surface temperature case nanofibers, Ts = 400K, lOnm. 

The superior fiber growth of CNH P4 compared to CN P4 is attributed to enhanced intermolecular interactions, that is, hydrogen bonding between the lone pair of 

It can be concluded that not only the functional group itself determines the growth behavior but also the counterpart functionalization has to be taken into account, leading to adjusted possibilities for intermolecular interactions. That only two positions are considered to be functionalized demonstrates the complexity of effects caused by functionalization.
