摘　　要：Controlling the shape of surface nanostructures is fundamental for various potential applications for cxamples,in water harvesting systems,liquid transportation or oil/water separation membranes.In this paper,the creation of porous surface structures is made by a process called templateless electropolymerization,in which water(H_(2)0)is oxidizedreduced to form gas(O_(2)/H_(2))bubbles onto the surfaces and acting as soft template for the polymer growth.Keeping the monomer(thieno[3,4-b]lhiophene)and the substituent(pyrene)constant,we demonstrate how a flexible PEG spacer can affect the structure shape.When the PEG spacer increases,the structures change frorm nanotubes(1D growth)to nanoribbons(2D)and after to hollow nanospheres(3D),which also affeets the wettig propertics.
