The invention provides a class of wedge-type block copolymers having a plurality of chemically different blocks, at least a portion of which incorporates a wedge group-containing block providing useful properties. For example, use of one or more wedge group-containing blocks in some block copolymers of the invention significantly inhibits chain entanglement and, thus, the present block copolymers materials provide a class of polymer materials capable of efficient molecular self-assembly to generate a range of structures, such as periodic nanostructures and microstructures. Materials of the present invention include copolymers having one or more wedge group-containing blocks, and optionally for some applications copolymers also incorporating one or more polymer side group-containing blocks. The present invention also provides useful methods of making and using wedge-type block copolymers.

The invention provides a class of block copolymers having a plurality of chemically different blocks, at least a portion of which incorporating polymer side chain groups having a helical secondary structure. The invention also provides structures generated by self-assembly of polymer blends including at least one block copolymer component, such as a brush block polymer or wedge-type block polymer. The invention provides, for example, periodic nanostructures and microstructures generated by self-assembly of block copolymers and polymer blends comprising a mixture of at least one block copolymer component, such as a brush block copolymer, and at least a second component.
