Claim Text:
1. A structure comprising a supramolecular assembly of a plurality of block copolymers; wherein each of said block copolymers independently comprises: a first polymer block comprising first repeating units; wherein each of said first repeating units of said first polymer block comprises a first polymer backbone group covalently linked to a first polymer side chain group or a first wedge group characterized by at least three branch points each terminating in an independent branch moiety comprising at least 10 atoms; said first wedge group having a molecular weight greater than or equal to 50 Da; and a second polymer block comprising second repeating units; wherein each of said second repeating units of said second polymer block comprises a second polymer backbone group covalently linked to a second wedge group or a second polymer side chain group that is different than said first wedge group or said first polymer side chain group; said second wedge group characterized by at least three branch points each terminating in an independent branch moiety comprising at least 10 atoms; and said second wedge group having a molecular weight greater than or equal to 50 Da; wherein said first and second repeating units are directly or indirectly covalently linked along a backbone of said block copolymer; wherein a domain length (DL) of the structure increases substantially linearly with molecular weight (MW) of said copolymer pursuant to the expression (E4) wherein 0.85<x<1: wherein said structure is characterized by at least one domain having a DL greater than 160 nm; wherein said structure absorbs, scatters or reflects electromagnetic radiation having wavelengths greater than or equal to 600 nm; wherein each of said block copolymers has a molecular weight selected from the range of 2,000,000 Da to 30,000,000 Da; and wherein each of said copolymers has the formula (FX1a): wherein: Z Q L A is independently a polymer side chain group or a wedge group, wherein A is said first wedge group or said first polymer side chain group; wherein B is said second polymer side chain group or said second wedge group; and each of n and m is independently an integer selected from the range of 10 to 2000.
