9408295 Pascal Three projects will be studied: (1) the use of nonplanar aromatic compounds as conformational switches, (2) the use of nitrogen-halogen donor-acceptor interactions in aromatic compounds, sometimes in combination with hydrogen bonds, for the control of molecular conformation and molecular association in the solid state and in solution, and (3) the synthesis of conformationally rigid, chiral molecular cavities. This grant from the Organic Dynamics Program supports the continuing research of Professor Robert A. Pascal, Jr. at Princeton University. Molecules will be prepared that will change their three-dimensional array in a controlled manner upon oxidation or reduction (the gain or loss of an electron) and by changing acidity. These molecules will form the basis of molecular switches, which may have practical importance. Another aspect of the work will directed to a study of attractive interactions between nitrogen and chlorine atoms in molecules. These interactions will have importance in the controlled assembly of molecules in solution and the solid-phase. In the final project, chiral molecular cavities will be prepared which can act as hosts to other chiral guest molecules. Chiral molecules are related as one's right and left hand.

9408295 PASCAL将研究三个项目：（1）将非平面芳香族化合物用作构象开关，（2）使用氮 ​​- 荷亚盐供体相互作用在芳族化合物中的相互作用，有时与氢键结合使用，以控制分子构象和分子结合的固体和分子结合（3）的构型和3（3）手性分子腔。 有机动力学计划的这项赠款支持普林斯顿大学的小罗伯特·帕斯卡（Robert A. Pascal，Jr。）的继续研究。将准备分子，以在氧化或还原（电子的增益或损失）和改变酸度时以受控方式改变其三维阵列。这些分子将构成分子开关的基础，这可能具有实际重要性。这项工作的另一个方面将针对分子中氮和氯原子之间有吸引力的相互作用的研究。这些相互作用将在溶液和固相中的分子组装中具有重要意义。在最后一个项目中，将制备手性分子腔，可以充当其他手性宾客分子的宿主。手性分子与左手和左手有关。
