合成了具有酮-烯醇互变异构现象的邻苯二酚和水杨基螺硼酸酯。研究了所合成的螺硼酸酯的荧光性质。这些螺硼酸酯在固态下表现出强的荧光，在溶液中表现出弱的荧光。这些螺硼酸酯显示出突出的聚集诱导发射活性，因为限制的分子内旋转的芳基环。水杨基螺硼酸酯比邻苯二酚螺硼酸酯具有更好的荧光性能。采用密度泛函理论（DFT）对配合物的结构、电子和光谱性质进行了研究. (C)2016爱思唯尔有限公司版权所有
Novel catechol and salicyl-spiroborates containing beta-ketoiminate ligand showing keto-enol tautomerism were synthesized. The fluorescent properties of the synthesized spiroborates were investigated. These spiroborates showed intense fluorescence in the solid-state and weak fluorescence in solution. These spiroborates showed prominent aggregation induced emission activity because of restricted intramolecular rotations of the aryl rings. The salicyl spiroborates showed better fluorescence property than the corresponding catechol spiroborates. The structural, electronic and spectroscopic properties were evaluated by using density functional theory (DFT). (C) 2016 Elsevier Ltd. All rights reserved.
