Dendrimer has numerous advantageous properties as new building block for bottom-up lithography approaches, associated with small feature size (sub-5nm), short stabilization times, and flexible functionalities and structures. In spite of the intense efforts in the field, it is difficult to generate large-area single domain ordering using dendrimer because of their complex architectures and multiple site for intermolecular interactions. This stands as a major hurdle for wide spread application of dendrimer materials. In the study, we report a simple method to create ultra-dense, single domain arrays cylinders over large areas by utilizing sandwich system. We also demonstrate for the first time use of a dendrimer assembly for the formation of a highly ordered nanoparticle array with a high areal density of ~20 Tdot/in2. We believe that the observations made in this effort should serve as the foundation for the design of new routes for bottom-up lithography based on dendrimers. |
