摘要
由于分子的三重激发态具有较长的寿命,允许激子长距离迁移,因此在光伏器件、光催化反应、分子传感和生物成像等领域具有广泛的应用前景。但三重激发态很容易受到环境,氧气等的影响,因此人们尝试利用各种方法来控制三重激发态的失活过程。我们的研究发现,利用四重氢键的非共价键作用[2],可以调控组装体内单重态-三重态双向能量传递过程;利用三重激发态易于被氧气淬灭的特点,我们首次报道了基于四重氢键超分子聚合物纳米小球的氧气探针。这种纳米探针在水中可均匀分散,对氧气具有高度的敏感性,高的稳定性和生物相容性,并且能够在细胞内比率式检测氧气。它具有制备简单,功能易于调控,易于降解等优点,因此可以扩展应用到其他重要分析物的检测上。[2]
The first phosphorescent quadruple hydrogen-bonded supramolecular polymer based oxygen nanoprobe(SPNP) is reported. The water-dispersible SPNPs are highly sensitive to oxygen, with full reversibility, excellent storage stability and photostability, good cell-penetrating ability, and exhibits low cytotoxicity toward living cells. The preparation of the SPNP is straightforward and its function is easily tunable by changing the monomeric structure. This work is expected to lead to the design of other SPNPs for other important analytes in biological systems.
