Nanoscale Heterogeneities in Nematic Azobenzene Polymethacrylates for Optical Nanowriting
ESR studies of the rotational dynamics of the cholestane spin probe dissolved in nematic azobenzene polymethacrylates from above TNI to below Tg are presented. Different dynamic regimes were recognized, in which the molecular sites or distributions of molecular sites were populated depending on the...

| description | ESR studies of the rotational dynamics of the cholestane spin probe dissolved in nematic azobenzene polymethacrylates from above TNI to below Tg are presented. Different dynamic regimes were recognized, in which the molecular sites or distributions of molecular sites were populated depending on the structure of the polymers and their thermal histories. We highlight the significance of such spatial‐temporal nanoscale heterogeneities in view of possible application of the azobenzene polymers in erasable optical nanowriting. |
