We first time prepared main‐chain type cage octasilsesquioxane (T₈) containing coordination polymers based on transition metal complexes with a bis‐Schiff base T₈ ligand (bis‐SA‐T₈), which was prepared from para‐bis(3‐aminopropyl)hexaisobutyl‐substituted T₈ cage (bis‐T₈) with salicylaldehyde. A mono‐Schiff base T₈ ligand (SA‐T₈) was prepared from 3‐aminopropylheptaisobutyl‐substituted T₈ cage (mono‐T₈) with salicylaldehyde. Coordination of bis‐SA‐T₈ with Cu²⁺ and Zn²⁺ in a solution as well as the film state was confirmed by the d–d transition appearing as broad shoulder on the longer wavelength at around 600 nm and the fluorescence at around 440–470 nm, respectively. The resulting metallosupramolecular polymers gave optically transparent films in the visible region by a casting method. However, opaque green and whitish films were obtained in the case of the Cu²⁺ and Zn²⁺ complexes with SA‐T₈, respectively. The thermal stabilities of the metallosupramolecular polymers were higher than those of the corresponding metal complexes of SA‐T₈. © 2019 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

在主链中掺入笼型倍半硅氧烷的金属超分子聚合物的合成

我们首次制备了基于过渡金属配合物的双链席夫碱T ₈配体（bis-SA-T ₈）的配位聚合物的主链型笼型_八聚倍半硅氧烷（T ₈），它是由对-bis（3-氨基丙基）六异丁基取代的T ₈笼（bis-T ₈）与水杨醛。由3-氨基丙基庚异丁基取代的T ₈笼（mono-T ₈）和水杨醛制备单Schiff碱T ₈配体（SA-T ₈）。的协调双- SA-T ₈与铜²⁺和Zn溶液中的²⁺以及薄膜状态通过d - d跃迁得以证实，其中d跃迁在较长波长处（约600 nm处）和宽于440-470 nm处的荧光处分别显示为宽肩。通过流延方法，所得的金属超分子聚合物在可见光区域中给出了光学透明的膜。但是，在分别具有SA-T ₈的Cu ²⁺和Zn ²⁺配合物的情况下，获得了不透明的绿色和发白的膜。金属超分子聚合物的热稳定性高于SA-T ₈相应金属配合物的热稳定性。分级为4 +©2019 Wiley Periodicals，Inc.J.Polym。科学，A部分：Polym。化学2019，57，2260年至2266年
