Abstract:
The present invention relates to photochromic compounds that include at least two photochromic moieties that are linked together by a multivalent linking group. The multivalent linking group can be selected so as to be flexible and/or substantially prevent electronic interaction between any two photochromic moieties through the multivalent linking group. The present invention also relates to photochromic compositions and articles that include at least a photochromic amount of one or more photochromic compounds of the present invention.
