Description:Literature Seminar\n\nPhotonic crystals are materials which pos
 sess a photonic band gap. When these band gaps are in the visible light re
 gime structural color arises\, precluding the need for toxic pigment or dy
 es to produce color. Structural color is widespread in nature with example
 s such as opal gemstones\, butterfly wings\, and responsive camouflage of 
 chameleons. Approaches to produce synthetic mimics have yielded precise ph
 otonic band gap materials\, but with the disadvantage of being expensive\,
  unscalable for industrial or commodity applications. In stark contrast\, 
 the well-known self assembly of block copolymers allows for scalability an
 d economical generation of photonic crystals. Coupled with the upsurge in 
 3-D printing technologies and significant synthetic advancements of block 
 copolymer higher order architectures\, polymers have become an attractive 
 route to produce structural color. Here a new 3-D printing platform is lev
 eraged to display the incredible tunability of block copolymers to selecti
 vely tune the photonic band gap and thus the structural color. The simple 
 adjustment of printing parameters and underlying kinetic mechanism that yi
 eld these versatile organic photonic materials will be discussed.\n\nZoom
