BASF To Develop Color Technology

Volume 90, Issue 27
BASF and Idea Zoo, a technology licensing firm, have agreed to jointly introduce and further develop Colr, a color-changing technology developed by Yadong Yin, an adviser to Idea Zoo. The technology’s colloidal iron oxide-based nanocrystals form a lattice of clusters. The photonic crystals’ color depends on the spacings in the lattice. By altering the lattice with a magnetic field, users of the technology are able to change the color of their products repeatedly, according to Idea Zoo. BASF will develop and manufacture the photonic crystals.
