Abstract
A method for limiting the transmission of light through a material is disclosed. In the method, a layer composed of a hyperbranched polymer formed via a copolycyclotrimerization reaction is interposed between a light source and the material. Also provided is a method for emitting light comprising exciting the hyperbranched polymer. In addition, methods for limiting the transmission of light and for emitting light using hyperbranched polymers formed by homopolycyclotrimerization reactions are disclosed. A new class of hyperbranched polymers produced by copolycyclotrimerization is also disclosed.
