    • This application relates to vaprochromic coordination polymers useful for analyte detection. The vapochromism may be observed by visible color changes, changes in luminescence, and/or spectroscopic changes in the infrared (IR) signature. One or more of the above chromatic changes may be relied upon to identify a specific analyte, such as a volatile organic compound or a gas. The chromatic changes may be reversible to allow for successive analysis of different analytes using the same polymer. The polymer has the general formula MW[M′X(Z)Y]N wherein M and M′ are the same or different metals capable of forming a coordinate complex with the Z moiety; Z is selected from the group consisting of halides, pseudohalides, thiolates, alkoxides and amides; W is between 1-6; X and Y are between 1-9; and N is between 1-5. Optionally, an organic ligand may be bound to M. In alternative embodiments of the invention M may be a transition metal, such as Cu and Zn, M′ may be a metal such as Au, Ag, Hg and Cu, and Z may be a pseuodohalide, such as CN, SCN, SeCN, TeCN, OCN, CNO and NNN. In one particular embodiment a new class of [Metal(CN)2]-based coordination polymers with vapochromic properties is described, such as Cu[Au(CN)2]2 and Zn[Au(CN)2]2 polymers.
    • 本申请涉及可用于分析物检测的色素配位聚合物。 可以通过可见的颜色变化,发光的变化和/或红外(IR)特征中的光谱变化来观察到紫外分析。 上述色度变化中的一种或多种可以依赖于鉴定特定分析物,例如挥发性有机化合物或气体。 色度变化可以是可逆的,以允许使用相同聚合物连续分析不同的分析物。 聚合物具有通式MW [M'X(Z)Y] N,其中M和M'是与Z部分形成配位络合物的相同或不同的金属; Z选自卤化物,拟卤化物,硫醇盐,醇盐和酰胺; W在1-6之间; X和Y在1-9之间; N为1-5。 任选地,有机配体可以结合到M.在本发明的备选实施方案中,M可以是过渡金属,例如Cu和Zn,M'可以是金属,例如Au,Ag,Hg和Cu,Z可以是 一种pseuodohalide,如CN,SCN,SeCN,TeCN,OCN,CNO和NNN。 在一个具体的实施方案中,描述了一类具有色相性质的[金属(CN)2]基配位聚合物,例如Cu [Au(CN)2] 2和Zn [Au(CN)2] 2聚合物)。
