Abstract

Platinum(II) complexes exhibit intense luminescence based on their molecular arrangement and chromic luminescence, which is a color change in response to gentle stimuli such as vapor exposure or weak mechanical forces. Both the molecular and the crystal designs for soft crystals are critical to effectively control the chromic phenomenon of platinum(II) complexes.

Platinum(II) complexes of square-planar geometry are interesting from a crystal engineering viewpoint because they exhibit strong luminescence based on the self-assembly of molecular units. The luminescence color changes in response to gentle stimuli, such as vapor exposure or weak mechanical forces. Both the molecular and the crystal designs for soft crystals are critical to effectively generate the chromic luminescence phenomenon of Pt(II) complexes. In this topical review, strategies for fabricating chromic luminescent Pt(II) complexes are described from a crystal design perspective, focusing on the structural regulation of Pt(II) complexes that exhibit assembly-induced luminescence via metal–metal interactions and structural control of anionic Pt(II) complexes using cations. The research progress on the evolution of various chromic luminescence properties of Pt(II) complexes, including the studies conducted by our group, are presented here along with the latest research outcomes, and an overview of the frontiers and future potential of this research field is provided.

基于发光铂(II)配合物的铬软晶体。

从晶体工程学的角度来看，方形平面几何的铂(II)复合物非常有趣，因为它们在分子单元自组装的基础上表现出强烈的发光特性。发光颜色会随着蒸汽暴露或微弱机械力等温和刺激而变化。软晶体的分子和晶体设计对于有效产生铂(II)配合物的色发光现象至关重要。在本专题综述中，从晶体设计的角度阐述了制造色度发光铂(II)配合物的策略，重点介绍了通过金属-金属相互作用对表现出组装诱导发光的铂(II)配合物进行结构调整，以及利用阳离子对阴离子铂(II)配合物进行结构控制。本文介绍了铂(II)配合物各种色度发光特性演变的研究进展，包括我们小组开展的研究，以及最新的研究成果，并概述了该研究领域的前沿和未来潜力。

期刊介绍： IUCrJ is a new fully open-access peer-reviewed journal from the International Union of Crystallography (IUCr). The journal will publish high-profile articles on all aspects of the sciences and technologies supported by the IUCr via its commissions, including emerging fields where structural results underpin the science reported in the article. Our aim is to make IUCrJ the natural home for high-quality structural science results. Chemists, biologists, physicists and material scientists will be actively encouraged to report their structural studies in IUCrJ.
