Switching in molecular shapes: main chain length driven rod-circle transition of isolated helical polysilanes.
Unique conformations such as rod, semicircle, and circle structures of isolated semi-flexible helical polysilanes were observed by atomic force microscopy (AFM); the chain topology was significantly related to the chain length (molecular weight) on the surfaces.
