摘要
随着化学及高新技术的发展，一门新兴的边缘学科超分子化学和器件正在引起理论和实验化学家的广泛重视［１］．超分子化学可定义为由多个分子通过分子间非键合作用而形成的复杂但有组织的体系［２］．目前，对这种由分子间“弱相互作用”形成的超分子的研究日益受到重视．...
In this investigation, mesoporous molecular sieve MCM\|41 was synthesized with tetraethyl orthosilicate(TEOS) as the source of silica and cetyltrimethylammonium bromide(CTABr) as the template for the first time by microwave radiation method . The products obtained by microwave radiation method gave similar XRD and SEM photograph with that by hydrothermally synthesized method. While our products possess a spherical hexagon and the diameter of the crystal powder is about 10 m. The encapsulation of the functional supramolecular material between MCM\|41 and rhodamine B was prepared under vacuum condition, the product was characterized by XRD, TG, IR, SEM and fluorescent spectrum. The results showed that the (RB)\++ ions have entered into the channel of MCM\|41 and formed the centers of luminescence, hence the functional supramolecular material with strong luminescence under UV excitation was obtained. The peak values of the excitation and emission spectra are 335\^2 and 587\^2 nm, respectively.
