For the preparation of 2D photonic crystals with high aspect ratios, polymer pillar arrays, in which both ends of nanopillars were supported by supporting layers, were introduced. The diameter, interval and length of nanopillar arrays could be controlled by changing the preparation conditions of anodic porous alumina templates. The reflection properties of the ordered polymer nanopillar array obtained exhibited a stop band in the spectrum, which corresponds to the band gap in the 2D photonic crystals.
