Acquisition of a Langmuir-Blodgett Instrument for Chemistry Research and Education

在主要研究仪器(MRI)收购计划的支持下，北肯塔基大学化学系将购买一台朗缪尔-布洛杰特仪器，用于制作多层薄膜。该仪器将用于调查1。)树枝状分子与血脑屏障模型系统的相互作用；涉及富勒烯和含过渡金属聚合物的有机金属超分子化学；官能化的[14]-环烯和4。磷脂单分子膜的物理性质和脂类/抑制剂的相互作用。朗缪尔-布洛杰特仪器提供了一个带有末端阻挡层的槽，用于制备和压缩单分子层和几个分子层厚的薄膜。它是由计算机控制的，允许无人监督地沉积未受污染的样品。然后，通过光谱和探针显微镜等其他技术对这些层进行研究和表征。该仪器将加强北肯塔基大学本科生的教学和研究。它将被整合到实验室课程中，包括高级乐器课程，并与准备要学习的材料的合成课程相结合。

With support from the Major Research Instrumentation (MRI) Acquisition Program, the Department of Chemistry at Northern Kentucky University will acquire a Langmuir-Blodgett instrument for the creation of multilayered films. The instrument will be used to investigate 1.) dendrimer interactions with blood-brain barrier model systems; 2.) organometallic supramolecular chemistry involving fullerenes and transition metal-containing polymers; 3.) the characterization of functionalized [14]-annulenes and 4.) the physical properties of phospholipids monolayers and lipid/inhibitor interactions. A Langmuir-Blodgett instrument provides a trough with end barriers to prepare and compress monolayers of molecules and thin films several molecular layers thick. It is computer controlled to allow unsupervised deposition of uncontaminated samples. The layers are then investigated and characterized by other techniques such as spectroscopy and probe microscopy. The instrument will enhance teaching and research of undergraduates at Northern Kentucky University. It will be integrated into lab courses including the upper level instrumental course and coupled to synthetic courses where materials to be studied will be prepared.
