Title:
NOVEL CROSSLINKED HEXAARYL BISIMIDAZOLE COMPOUND AND DERIVATIVE THEREOF, METHOD FOR PRODUCING THE COMPOUND AND PRECURSOR COMPOUND TO BE USED IN THE PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2010/061579
Kind Code:
A1
Abstract:
Provided is a crosslinked hexaaryl bisimidazole compound which can achieve photochromic characteristics, i.e., visually showing decoloring simultaneously with the stop of light irradiation, and enables precise control of color tone, density and so on in coloring.  Also provided are a method for producing the aforesaid compound whereby the degrees of freedom in molecular design and synthesis can be increased, and a precursor compound to be used in the production method.
