摘要

我们提出了一种简便的策略，通过交联工艺在有机硅支架中掺杂矿物酸（即硼酸和磷酸）来实现颜色可调的室温磷光（RTP）纳米探针。这种 RTP 纳米探针具有固有的可调磷光（420-650 纳米）、长寿命（发射持续约 5-15 秒，RTP 寿命：约 0.53-2.11 秒）和高量子产率（约 13.1-43.0%）。因此，制备的纳米探针可在活细胞中进行多重成像，信噪比高达约 52。

Mineral acid-triggered multicolor room-temperature phosphorescence nanoprobes for time-resolved bioimaging†

We present a facile strategy to achieve color-tunability room-temperature phosphorescence (RTP) nanoprobes by doping mineral acids (i.e., boric acid and phosphoric acid) in an organic silicon scaffold through a cross-linking process. Such RTP nanoprobes exhibit inherent tunable phosphorescence (from 420–650 nm) with long lifetime (emission lasting for ∼5–15 s, RTP lifetime: ∼0.53–2.11 s) and high quantum yields (∼13.1–43.0%). Therefore, the as-prepared nanoprobes enable multiple imaging in live cells with a high signal-to-background ratio value of ∼52.
