Tunable Full-Color Pixels: Bioinspired Electrochemically Tunable Block Copolymer Full Color Pixels (Adv. Mater. 30/2009)
The cover represents 1D periodic lamellar block-copolymer photonic gels swollen with methanol and acetic acid and laser-etched to form the outline of a squid. Edwin Thomas and co-workers show on p. 3078 that the gel displays different colors in different areas due to the variation of the relative amounts of the two solvents. In nature, real cephalopods (squid, octopus, and cuttlefish) have the ability to change the chemical environment around their one-dimensional reflectors thus creating naturally tunable photonic elements.
