In this paper we summarize our recent results on the self organized motion of a photosensitive polymeric liquid crystal. We studied the quality of pristine Langmuir-Blodgett molecular layers and their photoinduced dewetting. In particular we have found that the dewetting proceeds in very different ways depending on the initial film thickness: above a certain threshold a long range molecular flow is obtained, with mass transport over macroscopic distances. The resulting morphology comprises of a wide distribution of polymeric droplets, very polydispersed in size. On the contrary, below the threshold, the self-organized dewetting motion is quasi-local, resulting in a dense and uniform distribution of droplets of similar size. Finally, we discuss the quality of the molecular layers as a function of substrate pre-treatment, and of layer composition when a fraction of monomers is introduced. We discuss these results-relevant for the confinement of glass formers in monodispersed nanoparticles- also in the framework of thickness dependent melting phenomena, trying to elucidate the eventual role of the polymer mesogenicity in determining the observed phenomenology.
