Abstract
The present disclosure relates, according to some embodiments, to molecules, including substituted propenoic amides (e.g., aryl substituted propenoic amides), that may receive excited state energy from light-absorbing molecules. According to some embodiments, the present disclosure relates to molecules, including substituted propenoic amides (e.g., aryl substituted propenoic amides), that may quench, dissipate, and/or otherwise resolve excited state energy (e.g., as heat).
Claims20
A composition comprising:
- a photoactive molecule;
- and
- a substituted propenoic amide,
- wherein the propenoic amide has a structure according to Formula I:
- wherein R1 and R1′ are each, independently, a methoxyl group (—OCH3) or a hydrogen (H) with at least one being a methoxyl group (—OCH3),
- R2, R2′, R3, R3′, R4, R4′, R5, R5′ are each, independently, H, OH, alkyl, alkoxyl, or a substituted alkyl group,
- R6:
- is cyano or
- and
- R7 and R8 are each, independently, H, alkyl, substituted alkyl or a polymeric structure, and
- wherein the aryl substituted propenoic amide is configured (a) to resolve at least one excited state of the photoactive molecule without observable photochemical reaction, (b) to resolve at least one excited state of the photoactive molecule non-radiatively, or (c) to resolve at least one excited state of the photoactive molecule without observable photochemical reaction and non-radiatively;
- wherein the alkyl group may be selected from methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl (2-methylpropyl), t-butyl (1,1-dimethylethyl), and 3,3-dimethylpentane, straight chain hydrocarbon having from about 1 to about 30 (C1-C30) or more carbon atoms, or branched-chain hydrocarbon having from about 1 to about 30 (C1-C30) or more carbon atoms;
- wherein the polymeric structure may be selected from polyester, polyamide, polyurethane, polyacrylate, polystyrene, polyolefin, or any copolymer thereof;
- wherein the substituted alkyl group may have one or more substituents selected from heteroalkyl, ester, ether, carboxy, cyano, amino, amido, sulfur, halo, or any combination thereof.
