Abstract
Official abstract text for this publication.
This invention relates to electrochromic copolymers having a specific color transition prepared from precursors containing Si, Ge, Sn, or Pb, methods of producing such copolymers and precursors, and applications utilizing the copolymers to prepare electrochromic devices.
First claim
Opening claim text (preview).
What is claimed is: 1. A precursor mixture comprising: two precursors, wherein a first precursor is wherein Ar 1 is a heteroaryl electron donor unit; each occurrence of R 1 and R 2 is independently C 3 -C 12 alkyl, C 3 -C 122 haloalkyl, or aryl; X is O, S, (YR 1 R 2 ) x , or (CR a R b ) x wherein x is 0, 1, 2, 3, or 4, and R a and R b are independently hydrog…
