团结意味着力量：在新的硅溶胶发光体中，固体聚集体比孤立分子更强。固态发射可以通过改变发光源的分子结构来调节。取代基体积的增加削弱了分子间的相互作用，限制了分子内的旋转，导致发射颜色的蓝移和发射效率的大大提高（见图中的例子）。©2009 Wiley-VCH Verlag GmbH & Co. KGaA。
Solidarity means strength: In new silole luminogens, the solid aggregates are stronger emitters than isolated molecules. The solid-state emission is tunable by varying molecular structures of the luminogens. Increasing bulkiness of the substituents weakens intermolecular interactions and restricts intramolecular rotations, leading to a blue shift in emission color and a great increase in emission efficiency (see examples in picture). © 2009 Wiley-VCH Verlag GmbH & Co.
