英文摘要	Nonconventional organic luminogens have attracted a great deal of interests owing to their intriguing properties (e.g., unusual fluorescence emission) and promising applications. According to previous studies, it was found that introduction of Si-O could enhance the fluorescence emission of the luminogens. Herein, we have synthesized some fluorescent siloxane derivatives and similar molecules without Si-O units by simple and efficient modification to investigate the role of Si-O units in the emission. It was found that the strong emission could be observed in dilute solutions of siloxane derivatives, but not in the carbon compounds. UV/Vis absorption, fluorescence spectra, nuclear magnetic resonance spectra, and theoretical calculations indicated that the heteroatom and the Si-O unit formed the coordination bond in the siloxane derivatives, resulting in enhanced fluorescence emission.; National Natural Science Foundation of China [21274080, 21502105]; Natural Science Foundation of Shandong Province [ZR2015BQ008]; Shandong Special Fund for Independent Innovation and Achievements transformation [2014ZZCX01101]; SCI(E); ARTICLE; 11,SI; 1213-1217; 12
