Lamella-, cylinder-, and sphere-forming block copolymers (BCPs) of polystyrene-b-polybutadiene (PS-b-PBD) were drawn into the pores of anodized aluminum oxide (AAO) membranes in the melt by capillary forces. After thermal annealing, the nanorods of t

A series of light-emitting oligoacetylenic silanes and germanes containing fluorene units was investigated. It was found that the higher oligomers display lower band gaps and that the C Si(Ge) C bond permits π-electron delocalization. The π-d Si or
