COMPOSITIONS, APPARATUS, SYSTEMS, AND METHODS FOR RESOLVING ELECTRONIC EXCITED STATES

摘要

The present disclosure relates, according to some embodiments, to molecules, including conjugated fused polycyclic molecules, that may receive excited state energy from other molecules (e.g., light-absorbing molecules) or directly from the irradiation sources. According to some embodiments, the disclosure relates to molecules, including conjugated fused polycyclic molecules, that may resolve (e.g., quench, dissipate) excited state energy, normally by way of releasing it as heat. (e.g., as heat). Conjugated fused polycyclic molecules of various structures are disclosed including Formula III:;;The disclosure further relates to methods of use and/or therapy using molecules of Formulas I, II, and/or III.

1. A composition comprising:
a photoactive molecule; and a conjugated fused polycyclic molecule, wherein the conjugated fused polycyclic molecule has a structure according to Formula I:wherein
R1 is independently nitrile, C(O)R3, C(O)N(R4)R5, C(O)—S—R6, or fused aryl, R2 is independently nitrile, C(O)R7 C(O)N(R8)R9, C(O)—S—R10, or fused aryl, R3, R4, R5, R6, R7, R8, R9, and R10 are each independently H, aryl, substituted aryl, fused aryl, alkyl, substituted alkyl, or branched alkyl, D1 is independently H, hydroxyl, or R11, D2 is independently H, hydroxyl, or R12, and R11 and R12 are each independently H, alkyl, heteroalkyl, alkoxyl, heteroalkoxyl, aryl, heteroaryl, or fused aryl,provided that
R1 and R2 are not both nitrile, R1 and R2 are not fused to each other, R11 and R12 do not comprise azo, the fused tricyclic moiety defined by rings X, Y, and Z is the only tricyclic moiety in the molecule, and D1 and D2 are not fused to each other,wherein the conjugated fused polycyclic molecule is configured (a) to resolve at least one excited state of the photoactive molecule substantially without observable photochemical reaction, (b) to resolve at least one excited state of the photoactive molecule substantially non-radiatively, or (c) to resolve at least one excited state of the photoactive molecule substantially without observable photochemical reaction and substantially non-radiatively.
