    摘要： The disclosure relates to a substituted cyclooctatetraene triplet excited-state quencher compound of Formula (I): wherein: Z is a wide band gap moiety; L is a non-conjugating linker group; each R, which may be the same or different, is a non-conjugating substituent; n is an integer from 0 to 7; and m is an integer from 1 to 6. The disclosure further relates to use of such compounds as triplet quenchers, compositions comprising such compounds, films or coatings comprising said compounds or compositions, and use of said compositions or films or coatings as active gain media for light amplification.

    摘要： A compound of Formula I




    wherein:
    ring B is a 5-membered heterocyclic ring, or a 6-membered carbocyclic ring;
    each of X1 and X2 is independently C, CR, or N, with at least one of them being C;
    each of X3-X11 is independently C, CR, or N, with at least one of them being N, and two adjacent of X3-X7 are carbon-fused to the shown moiety through the linkage indicated by the two squiggly lines;
    Y is selected from the group consisting of O, S, Se, NR′, CR′R″, and SiR′R″;
    each of RA and RB independently represents zero, mono, or up to a maximum allowed substitution to its associated ring;
    each of R, R′, R″, RA, and RB is independently a hydrogen or a substituent selected from the group consisting of —SiR1R2R3 or —GeR1R2R3, deuterium, halogen, alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, boryl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carboxylic acid, ether, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof, with at least one of RA or RB comprising —SiR1R2R3 or —GeR1R2R3;
    each of R1, R2, and R3 is independently selected from the group consisting of alkyl, aryl group, heteroaryl group, and combinations thereof; and
    any two substituents are optionally joined or fused to form a ring where chemically feasible.
