摘要： A photochromic grey coloring 2H-naphtho[1,2-b]pyran of formula (1) wherein R1 is selected from mono-, di- or poly-substituted aryl groups, mono-, di- or poly-substituted naphthyl groups and mono-, di- or poly-substituted heteroaryl groups, wherein at least one substituent is a nitrogen containing group, including amino, C1-C20 and C6-C20 alkylamino, C1-C20 and C6-C20 dialkylamino, C2-C20 dialkenylamino, C2-C20 or C4-C20 di(polyalkenyl)amino, arylamino, diarylamino, C1-C20 alkylarylamino, tetra (C1-C10 linear or branched alkyl) guanidino and cyclic-amino groups and at least one of R7 and R9, which may be the same or different, is selected from C1-C20 N alkylamino C1-C20 N-alkylamido, C1-C20 N,N-dialkylamido, amido, nitro, amino, C1-C20 alkylamino, C1-C20 dialkylamino, C2-C20 dialkenylamino, C4-C20 di(polyalkenyl)amino, arylamino, diarylamino, C1-C20 alkylarylamino, or cyclicamino groups. The compounds may be combined with a polymeric host material such as plastic or glass to make a sunglass lens, an ophthalmic lens or a window. The compounds may also be included in an ink or a fuel.
