Photonic technologies are nowadays dominated by highly performing inorganic structures that are commonly fabricated via lithog. or epitaxial growth. Unfortunately, the fabrication of these systems is costly, time consuming, and does not allow for the growth of large photonic structures. All-polymer photonic crystals could overcome this limitation thanks to easy solubility and melt processing. On the other hand, macromols. often do not offer a dielec. constant large enough to approach the performances of their inorganic counterparts. In this work, the authors demonstrate a new approach to achieve high dielec. constant distributed Bragg reflectors with a photonic band gap that is tunable in a very broad spectral region. A highly transparent medium was developed through a blend of a com. polymer with a high refractive index inverse vulcanized polymer that is rich in sulfur, where the large polarizability of the S-S bond provides refractive index values that are unconceivable with common non-conjugated polymers. This approach paves the way to the recycling of sulfur byproducts for new high added-value nanostructures. In the experiment, the researchers used 2,5-Dibromothiophene(cas: 3141-27-3Product Details of 3141-27-3)
2,5-Dibromothiophene(cas: 3141-27-3) , is mainly used as pharmaceutical intermediate and synthesis intermediate. 2,5-Dibromothiophene polymerizes by debromination with magnesium catalyzed by nickel compounds to form poly(2,5- thienylene) .Product Details of 3141-27-3
