Abstract:
The photostabilizing electronic excited state energy—particularly singlet state energy from a UV-absorbing molecule has been found to be readily transferred to (accepted by) α-cyanodiphenylacrylate compounds of formulas (I) and (V) having an alkoxy radical preferably in the four (para) position (hereinafter methoxycrylenes) on one or both of the phenyl rings: wherein at least one of R1 and R2 is a straight or branched chain C1-C12 alkoxy radical, preferably C1-C8, more preferably C1-C4, and most preferably methoxy, and any non-alkoxy radical R1 or R2 is hydrogen; and R3 is a straight or branched chain C1-C24 alkyl radical, preferably C12-C24, more preferably C20; wherein A and B are the same or different and are selected from the group consisting of oxygen, amino and sulfur; R1 and R3 are the same or different and are selected from the group consisting of C1-C30 alkyl, C2-C30 alkylene, C2-C30 alkyne, C3-C8 cycloalkyl, C1-C30 substituted alkylene, C2-C30 substituted alkyne, aryl, substituted aryl, heteroaryl, heterocycloalkyl, substituted heteroaryl and substituted heterocycloalkyl; R2 is selected from the group consisting of C1-C30 alkyl, C2-C30 alkylene, C2C30 alkyne, C3-C8 cycloalkyl, C1-C30 substituted alkyl, C3-C8 substituted cycloalkyl, C1-C30 substituted alkylene, C2-C30 substituted alkyne; R4, R5, R6 and R7 are the same or different and are selected from the group consisting of C1-C30 alkoxy straight chin on branched and a, b, c and d are each either 0 or 1, and a, b, c and d add up to 1, 2, 3, or 4.
