SGER: A Surface-Mounted Molecular Turbine

科罗拉多大学博尔德分校的Josef Michl教授得到了分析和表面化学项目探索性研究（SGER）的小额资助，以研究利用分子尺度涡轮机在纳米空间尺度上移动液体的可能性。这个想法是把一个类似螺旋桨的分子拴在一个表面上，当气体或液体流过表面时，用偏振荧光作为探针来测量螺旋桨的运动。难点在于如何让螺旋桨单向移动。这个分子是一个修饰过的二乙基三烯。下一步是使用光脉冲来驱动分子涡轮机。这些分子可以作为泵，应用于分析化学、分离科学和生物化学。

Professor Josef Michl of the University of Colorado at Boulder is supported with a Small Grant for Exploratory Research (SGER) from the Analytical and Surface Chemistry Program to study the possibility of utilizing molecular-scale turbines to move liquids on a nanoscopic spatial scale. The idea is to tether a propeller-like molecule to a surface and to measure the motion of the propeller using polarized fluorescence as a probe as gas or liquid is flowed over the surface. The challenge is to get the propeller to move unidirectionally. The molecule will be a modified diethynyltriptycene. The next step is to use light pulses to drive the molecular turbines. The molecules could act as pumps, with applications in analytical chemistry, separations science and biochemistry.
