Abstract

A binuclear Au-P complex [Au₂(2-bdppmapy)₂](PF₆)₂ (1) was synthesised by the reaction of 2-bdppmapy (N,N'-bis-(diphenylphosphanylmethyl-2-aminopyridine) with AuCN and [Cu(MeCN)₄]PF₆. The solid phase of 1 emitted bright yellow phosphorescence at λ_max = 580 nm under UV excitation (QY = 4.41%, τ = 1.88 μs), which shifted to green (λ_max = 551 nm, QY = 5.73%) after being pressurised under 5 MPa. This colour change was recoverable upon exposure to CH₂Cl₂ vapor. Similar mechanochromic photoluminescence behaviour was observed after grinding the crystals of 1. A filter paper impregnated with 1 demonstrated recyclable write/erase functionality for encrypted information transfer.

一种Au-P配合物的可恢复和敏感压力诱导的机械致色光致发光。

以2-bdppmapy (N，N′-双-（二苯基磷酰甲基-2-氨基吡啶）与AuCN和[Cu(MeCN)4]PF6为原料合成了双核Au-P配合物[Au2(2-bdppmapy)2](PF6)2(1)。1的固相在紫外激发下（QY = 4.41%, τ = 1.88 μs）在λmax = 580 nm处发出亮黄色磷光，在5 MPa下加压后变为绿色（λmax = 551 nm, QY = 5.73%）。这种颜色变化在暴露于CH2Cl2蒸气时是可恢复的。研磨1。一种浸渍了1的滤纸，演示了用于加密信息传输的可回收写/擦除功能。

期刊介绍： Molecules (ISSN 1420-3049, CODEN: MOLEFW) is an open access journal of synthetic organic chemistry and natural product chemistry. All articles are peer-reviewed and published continously upon acceptance. Molecules is published by MDPI, Basel, Switzerland. Our aim is to encourage chemists to publish as much as possible their experimental detail, particularly synthetic procedures and characterization information. There is no restriction on the length of the experimental section. In addition, availability of compound samples is published and considered as important information. Authors are encouraged to register or deposit their chemical samples through the non-profit international organization Molecular Diversity Preservation International (MDPI). Molecules has been launched in 1996 to preserve and exploit molecular diversity of both, chemical information and chemical substances.
