Red-emitting oxazine fluorophores are shown to bind to cucurbit[7]uril (CB[7]) with high affinity. Their fluorescence quantum yield and lifetime are thereby enhanced owing to shielding of the dyes from water. Using CB[7] as an imaging additive leads to a larger number of photons detected per molecule in super-resolution experiments with the dye ATTO655.

使用葫芦脲封装的荧光团进行超分辨率成像


红色发射的恶嗪荧光基团显示以高亲和力与葫芦[7]uril （CB[7]）结合。由于染料被水屏蔽，它们的荧光量子产率和寿命因此得到提高。使用 CB[7] 作为成像添加剂会导致在染料ATTO655的超分辨率实验中每个分子检测到更多的光子。
