| titleOfInvention | Dihydroquinoline photochromic compounds |
| abstract | The present invention relates to a photochromic compound having a core fused ring structure represented by at least one of the following Formula (Ia) or Formula (IIa), (Ia) (IIa) Independently for each of Formula (Ia) and Formula (IIa): R1 is in each case independently selected from substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, -SO2R5, or -C(O)-XR5, where, X is selected from a single bond, -N(R5)-, or -O-, and R5 in each case is independently selected from hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted aryl, or substituted or unsubstituted heteroaryl; and B and B' are each independently selected from substituted or unsubstituted alkenyl, substituted or unsubstituted alkynyl, substituted or unsubstituted aryl, or substituted or unsubstituted heteroaryl. The present invention also relates to photochromic compositions and articles including such photochromic compounds. |
