METHOD FOR ENHANCING PHOTOSENSITIVITY OF PHOTOCHROMIC MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a photochromic molecule having enhanced photosensitivity for the purpose of obtaining practical color development density, and to provide a method for enhancing photosensitivity of the molecule. SOLUTION: An electron donating functional group is introduced into an imidazole ring of a photochromic molecule having a paracyclophane skeleton so as to produce a molecular orbital in a high level greatly overlapping with the lowest unoccupied molecular orbital (LUMO).
