Photoinduced electron transfer voltage-sensitive compounds

A compound comprising the structure of Formula II:

• wherein,
• L1 is selected from the group consisting of:
• and any combination of the foregoing;
• A1, A4-A10 are each independently selected from CH2, CHR′, CR′2, NH, O, S, Se, Te, SiH2, SiHR′, SiR′2, GeH2, GeHR′, GeR′2, SnH2, SnHR′, SnR′2, PbH2, PbHR′, or PbHR′2, wherein R′ is selected from the group consisting of D, optionally substituted FG, optionally substituted (C1-C12)alkyl, optionally substituted (C1-C11)heteroalkyl, optionally substituted (C1-C12)alkenyl, optionally substituted (C1-C11)heteroalkenyl, optionally substituted (C1-C12)alkynyl, and optionally substituted (C1-C11)heteroalkynyl;
• A2 is selected from NH2, S or O;
• A3 is selected from NH2, OH, SH and methoxy;
• X1-X39 are independently selected from N or C, wherein when an X group is an N, then the R group is absent;
• and
• R1-R47 are independently selected from H, D, optionally substituted FG, optionally substituted (C1-C12)alkyl, optionally substituted (C2-C10)heteroalkyl, optionally substituted (C1-C12)alkenyl, optionally substituted (C2-C10)heteroalkenyl, optionally substituted (C1-C12) alkynyl, optionally substituted (C2-C10)heteroalkynyl, optionally substituted (C3-C12)cycloalkyl, optionally substituted (C5-C12)cycloalkenyl, optionally substituted aryl, optionally substituted heterocycle, optionally substituted mixed ring system, wherein one or more adjacent R groups can be linked together to form one or more substituted rings selected from the group comprising (C3-C12)cycloalkyl, (C3-C12)cycloalkenyl, heterocycle, aryl, and mixed ring system;
• and
• n1-n8 are independently an integer selected from 0 to 10.
