Metallized hyperbranched polydiyne: a photonic material with a large refractive index tunability and a spin-coatable catalyst for facile fabrication of carbon nanotubes†
Abstract
A cobalt-containing hyperbranched polydiyne shows refractive indexes (n) as high as 1.713–1.813 in the long wavelength region, which can be tuned to a large extent (Δn up to ∼0.048) by UV irradiation; the
