    摘要: The present invention relates to a photochromic compound comprising:
    (a) at least one photochromic group chosen from a pyran, an oxazine, and a fulgide; and
    (b) at least one lengthening agent L 2 attached to the at least one photochromic group, the at least one lengthening agent L 2 represented by:

            - [S] s' -P'     (I)

    wherein:
    (i) P' is a group chosen from steroid radicals, terpenoid radicals, alkaloid radicals, and liquid crystal mesogens; and
    (ii) s' is chosen from 0 to 20, and each S is independently chosen for each occurrence from a spacer unit chosen from:
    (A) -(CH 2 ) g -, -(CF 2 ) h -, -Si(CH 2 ) g -, -(Si[(CH 3 ) 2 ]O) h -, wherein g is independently chosen for each occurrence from 1 to 20; h is a whole number from 1 to 16 inclusive;
    (B) -N(Z)-, -C(Z)=C(Z)-, -C(Z)=N-, -C(Z')-C(Z')-, wherein Z is independently chosen for each occurrence from hydrogen, C 1 -C 6 alkyl, cycloalkyl and aryl, and Z' is independently chosen for each occurrence from C 1 -C 6 alkyl, cycloalkyl and aryl; and
    (C) -O-, -C(O)-, -C≡C-, -N=N-, -S-, -S(O)-, -S(O)(O)-, straight-chain or branched C 1 -C 24 alkylene residue, said C 1 -C 24 alkylene residue being unsubstituted, mono-substituted by cyano or halo, or poly-substituted by halo;

    provided that when two spacer units comprising heteroatoms are linked together the spacer units are linked so that heteroatoms are not directly linked to each other.
