： WO 3 is an ideal inorganic electrochromic material. Its electrochromic mechanism is reversible redox re⁃ action under the driving of voltage ， accompanied by the insertion and extraction of counterions in the material. In this paper ， we investigated the electrochromic properties of amorphous WO 3 in three aqueous electrolyte solutions of Li ， Zn and Al. WO 3 achieves the best electrochromic performances when Al 3+ was used as insertion ions ， including fast response speed （ 2. 8 s for coloring and 1. 1 s for decolorization ）， large optical contrast （ 83. 4% at 700 nm ）， good cycling stability （ 2. 8% decay for 1 000 successive cycles ）， high coloration efficiency （ 74. 7 cm 2 · C -1 ）， and its comprehensive performance is at high level among the reported WO 3 electrochromic devices. Mechanistic studies have revealed that the enhanced performance in Al 3+ electrolytes is due to the fast ion transport kinetics. These re⁃ sults will provide a simple and effective guidance for the construction of high - performance electrochromic devices and the optimization of electrolytes
wo3是一种理想的无机电致变色材料。其电致变色机理是电压驱动下的可逆氧化还原再作用，伴随着材料中反离子的插入和抽取。本文研究了无定形wo3在Li、Zn和Al三种水溶液中的电致变色性能。以Al 3+作为插入离子时，wo3的电致变色性能最佳，响应速度快(2)。8分上色，1分。1 s脱色)，大的光学对比度(83。在700 nm下，4%)，良好的循环稳定性。在1000个连续循环中衰减8%)，显色效率高(74。7 cm 2·C -1)，综合性能在已报道的wo3电致变色器件中处于较高水平。机理研究表明，Al - 3+电解质的性能增强是由于离子的快速传输动力学。这些结果将为高性能电致变色器件的构建和电解液的优化提供简单有效的指导

： Three novel linear dimeric luminescent materials ， BtCzPPQ ， DCPPQ and PZPPQ ， were synthesized by linking two quinoline receptors together into an electron acceptor （ A ） using the Suzuki coupling reaction ， and by linking donor groups （ D ） with different electronic donated moiety. All the three materials have good rigidity ， thermal stability （ T g >220 ℃ ）， and high photoluminescence quantum yields （ PLQYs more than 70% ） . The effects of structur⁃ al factors such as the rigidity of molecules ， linear length ， and the donor group on the electroluminescence properties of the materials were analyzed by characterizing the orbital distribution ， thermal stability ， and photophysical proper⁃ ties of the materials.
