由于有效的通过键能量转移（高达99%），两个能量转移盒表现出较大的伪斯托克斯位移（高达400nm）。Fe（III）与供体实体的选择性结合显著抑制激发能转移，导致水溶液和活细胞中的荧光猝灭。
Two energy transfer cassettes that exhibit a large pseudo Stokes' shift (up to 400 nm) due to efficient through-bond energy transfer (up to 99%) have been constructed. Selective binding of Fe(III) with the donor entity significantly suppresses the excitation energy transfer resulting in fluorescence quenching in aqueous solution and in living cells.
