    Abstract: Methods of directed self-assembly of multi-block (i.e., triblock and higher-order) copolymers on patterned substrates and related compositions are provided. According to various embodiments, the methods involve depositing copolymer materials on substrates configured to drive the assembly of micro-phase separated films that exhibit the same morphology as that copolymer materials in the bulk. In certain embodiments, binary patterns are used to drive the triblock copolymer films. The binary two-dimensional surface patterns are transformed into three-component and three-dimensional structures throughout the thickness of the overlying copolymer films.
