Abstract:
A method of quenching excited state energy from a photodegradable pigment that has been excited by absorption of light having a wavelength in the wavelength range of 290-800 nm, comprising reacting a pigment with a conjugated fused tricyclic compound having electron withdrawing groups of Formula (II) or a salt thereof: wherein:         A is selected from the group consisting of O, S, C═O, C═S,           B 1 , B 2 , D 1  and D 2  are each independently selected from the group consisting of F, Cl, Br, I, CF 3 , CC13, NR33+, NO2, CN, C(=0)R4, C(═O)OR′, SO2R5, aryl, and —C═CHR6; each m independently is 0, 1, 2, 3, or 4; a is 0 or 1; each R′ is independently selected from the group consisting of LI, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, and aryl; R 2  is selected from the group consisting of H, alkyl, cycloalkyl, alkenyl, alkynyl, and aryl; each R 3  is independently selected from the group consisting of H and C 1 -C 6  alkyl; each R 4  is independently selected from the group consisting of H, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, and aryl; each R 5  is independently selected from the group consisting of H, O, OH, NH 2 , and Cl; and each R 6  is-independently selected from the group consisting of alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, and aryl.

Claim (Index 3):
A method of protecting skin from oxidative stress caused by the photogeneration of a reactive oxygen species from the group consisting of singlet oxygen, superoxide anion, peroxide, hydroxyl radical, hydroxyl ion, and mixtures thereof, comprising coating the skin with a pigment excited state quencher capable of accepting or donating an electron from or to a pigment compound in the excited state and returning the excited pigment compound to its ground state, said pigment quencher comprising a conjugated fused tricyclic compound having electron withdrawing groups of Formula (II) or a salt thereof: wherein: A is selected from the group consisting of O, S, C\u2550O, C\u2550S, B 1 , B 2 , D 1 , and D 2  are each independently selected from the group consisting of F, Cl, Br, I, CF 3 , CCl 3 , NR 3 3 + , NO 2 , CN, C(\u2550O)R 4 , C(\u2550O)OR 1 , SO 2 R 5 , aryl, and \u2014C\u2550CHR 6 ; each m independently is 0, 1, 2, 3, or 4; n is 0 or 1; each R 1  is independently selected from the group consisting of H, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, and aryl; R 2  is selected from the group consisting of H, alkyl, cycloalkyl, alkenyl, alkynyl, and aryl; each R 3  is independently selected from the group consisting of H and C 1 -C 6  alkyl; each R 4  is independently selected from the group consisting of H, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, and aryl; each R 5  is independently selected from the group consisting of H, O\u2014, OH, NH 2 , and Cl; and, each R 6  is independently selected from the group consisting of alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, and aryl.
