A new class of amphiphilic anionic platinum(II) bzimpy complexes has been demonstrated to show aggregation in water through Pt···Pt and π-π stacking interactions. An interesting aggregation-partial deaggregation-aggregation process and a morphological transformation from vesicles to nanofibers have been demonstrated. These changes can be systematically controlled by the variation of solvent composition and could readily be probed by UV-vis absorption, emission, NMR, transmission electron microscopy, and even with our naked eyes.
一类新型两亲性阴离子铂(II) bzimpy 配合物已被证明可通过 Pt···Pt 和 π-π 堆积相互作用在水中聚集。已经证明了一个有趣的聚集-部分解聚集-聚集过程和从囊泡到纳米纤维的形态转变。这些变化可以通过溶剂组成的变化来系统地控制，并且可以通过紫外-可见吸收、发射、NMR、透射电子显微镜，甚至肉眼轻松探测到。
