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）使用非平面 芳香族化合物作为构象开关，（2）使用 氮-卤素给体-受体相互作用 化合物，有时与氢键结合， 分子构象的控制和分子 在固态和溶液中的缔合，和（3） 构象刚性手性分子合成 蛀牙 有机动力学计划的这笔赠款支持 罗伯特·A教授的研究。小帕斯卡在 普林斯顿大学。分子将被准备好， 以受控的方式更改其三维阵列 在氧化或还原时（ 电子）和通过改变酸度。这些分子会形成 分子开关的基础，这可能具有实际意义， 重要性工作的另一个方面将针对一个 氮原子与氮原子间吸引作用的研究 分子中的氯原子。这些互动将有 在控制分子组装中的重要性， 溶液和固相。在最后一个项目中，手性 制备分子空腔， 其他的手性客体分子。手性分子是 像某人的右手和左手一样相关。
