摘要

具有多光输出的发光开关对于满足日益增长的高安全性加密需求至关重要。本文通过将发光的平面Pt(II)基团整合到SS/ rr -反式-1,2-环己烷二胺支架中,设计并合成了对称手性分子。这种方法可以使这些材料的结构、组件和光学/风热性质相互关联,这些材料表现出依赖于间隔的光学和风热行为。刚性更强的折叠体表现出不同寻常的从单体到分子内准分子的光转换,以及相应的圆二色性和圆偏振发光,随着温度的升高,与传统的发光发色团明显不同。基于其可逆和敏感的多色磷光特性,采用刚性分子折叠体制造出逐步防伪的油墨,推进了高安全性的防伪技术。

Unusual Optical Switches of Platinum(II) Foldamers for Stepwise Photonic Information Storage Materials

Unusual Optical Switches of Platinum(II) Foldamers for Stepwise Photonic Information Storage Materials

Luminescent switches with multiple optical outputs are essential for meeting the growing demand for high-security encryption. Herein, symmetric and chiral molecules are designed and synthesized by integrating luminescent planar Pt(II) moieties into SS/RR-trans-1,2-cyclohexane diamine scaffolds. This approach enables correlation of the structures, assemblies, and optical/chiroptical properties of these materials, which exhibit spacer-dependent optical and chiroptical behavior. The more rigid foldamer shows unusual optical switching from the monomer to intramolecular excimers and the corresponding circular dichroism and circularly polarized luminescence with increasing temperature, differing significantly from conventional luminescent chromophores. Based on its reversible and sensitive multicolor phosphorescence characteristics, the rigid molecular foldamer is employed to create a stepwise anticounterfeit ink, advancing high-security anti-counterfeiting technology.
