    • The lack of this effect for the DETX-sensitized reactions is likely due to the higher concentration of DETX (∼4 wt , which will tend to favor energy transfer to nearby sensitizers (P*, S → P, S*) over energy transfer to nearby co-sensitizers (P*, C → P, C*) when ET(C) > ET(S) and [S] ≈ [C

    • The measured rate constant for energy transfer, kq, from KC* to DB3 in ethyl acetate is 2 × 108 M -1 s-1. According to eq 9 in ref 4, kq, kd ket/ket, k-d, where ket is the first-order rate constant for triplet energy transfer in an encounter of KC* and DB3, kd is the rate constant for diffusional formation of the encounter/cage complex, and k-d is the rate constant for dissociation of the encounter/cage pair. Taking kd as 1.5 × 1010 M-1 s-1 and k-d as 3 × 1010 s-1 in ethyl acetate4 yields a value forint of 4 × 108 s-1. This value corresponds to the rate constant for triplet energy transfer within a solvent cage where KC* and DB
