| titleOfInvention | Method of quenching electronic excitation of chromophore-containing organic molecules in photoactive compositions |
| 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: n n n n n n n n n n wherein at least one of R 1 and R 2 is a straight or branched chain C 1 -C 12 alkoxy radical, preferably C 1 -C 8 , more preferably C 1 -C 4 , and most preferably methoxy, and any non-alkoxy radical R 1 or R 2 is hydrogen; and R 3 is a straight or branched chain C 1 -C 24 alkyl radical, preferably C 12 -C 24 , more preferably C 20 ; n n n n n n n n n n wherein A and B are the same or different and are selected from the group consisting of oxygen, amino and sulfur; R 1 and R 3 are the same or different and are selected from the group consisting of C 1 -C 30 alkyl, C 2 -C 30 alkylene, C 2 -C 30 alkyne, C 3 -C 8 cycloalkyl, C 1 -C 30 substituted alkylene, C 2 -C 30 substituted alkyne, aryl, substituted aryl, heteroaryl, heterocycloalkyl, substituted heteroaryl and substituted heterocycloalkyl; R 2 is selected from the group consisting of C 1 -C 30 alkyl, C 2 -C 30 alkylene, C 2 C 30 alkyne, C 3 -C 8 cycloalkyl, C 1 -C 30 substituted alkyl, C 3 -C 8 substituted cycloalkyl, C 1 -C 30 substituted alkylene, C 2 -C 30 substituted alkyne; R 4 , R 5 , R 6 and R 7 are the same or different and are selected from the group consisting of C 1 -C 30 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. |
