Molecules, compositions, and methods for light absorption
View Patent ↗Embodiments provided herein relate to molecules, compositions, and methods for light absorption. In some embodiments, the molecules and/or compositions can be used to absorb ultraviolet light. In some embodiments, the ultraviolet light absorption compound can be used in a sunscreen composition. In some embodiments, the compound includes an azobenzene group for the absorption of ultraviolet light.
1. A molecule comprising an azobenzene group attached to a heterocycle group and a cholesterol group wherein the azobenzene group has the formula of Formula I:
wherein R1 comprises a heterocycle group or a substituted variant thereof and wherein R2 comprises a cholesterol group or a substituted variant thereof, and, wherein the heterocycle group is selected from Formula II, VI, VII, VIII, or IX:
wherein n=1 or 2, and wherein R3 is either no substitution or a phenyl group,
2. The molecule of claim 1 , wherein the heterocycle is connected to the structure of Formula I via an alkoxy member.
3. The molecule of claim 2 , wherein the alkoxy member comprises 1, 2, 3, 4, 5, 6, 7, or 8 carbons.
4. The molecule of claim 3 , wherein the heterocycle group comprises the structure shown in Formula II:
wherein n=1 or 2, and wherein R3 is either no substitution or a phenyl group.
5. The molecule of claim 4 , wherein R3 can be in the ortho-position or meso-position to the nitrogen.
6. The molecule of claim 1 , wherein the cholesterol group is selected from the group consisting of:
7. The molecule of claim 5 , wherein the cholesterol group comprises the structure of Formula III:
8. The molecule of claim 1 , wherein the molecule comprises the structure of Formula IV:
wherein n=1 or 2 and wherein R3 is either no substitution or a phenyl group.
9. The molecule of claim 1 , wherein the molecule comprises the structure of Formula V:
wherein n=1 or 2, and wherein R3 is either no substitution or a phenyl group, and wherein when the when R3 is a phenyl group, the phenyl is in the ortho or meso-position to the nitrogen in the heterocycle.
