Title:
ペンタアリールビイミダゾール化合物および該化合物の製造方法
Document Type and Number:
Japanese Patent JP6489461
Kind Code:
B2
Abstract:
In order to address the problems of conventional photochromic compounds, which are the insufficient coloring/discoloring speed and durability exhibited thereby and the large number of production steps, the present invention provides a photochromic compound that exhibits a high speed coloring/discoloring reaction and high durability while it is able to be synthesized in low cost, and that has industrial applicability. The compound of the present invention is characterized by the insertion of a diarylimidazolyl radical into the ortho position of an aryl group. The compound exhibits photochromic properties, and achieves a photochromic compound having both a high speed color switching reaction and high durability. Furthermore low cost synthesis is possible, and the photochromic compound has industrial applicability.
