量子点在Nematic Liquid Crystal中的定向自组装

Directed Self-Assembly of Quantum Dots in a Nematic Liquid Crystal

Rajratan Basu, Germano S. Iannacchione

摘要:

自组织各向异性双折射液晶(LC)诱导自组装在量子点(QD)上形成沿双折射指向矢的一维链。量子点的空间排序,实现在的CPLLC矩阵,可以控制在一个优选的方向上施加的电场,获得更好的自组装。一旦电场消失,LC+QD系统就会弛豫回到原始状态,揭示出内在动力学。由于系统的介电各向异性,这种动态响应可以通过研究介电弛豫来捕获。所研究的动态响应揭示了场诱导自组装机制和LC+QD系统的稳定性的见解。

英文摘要:

Self organizing anisotropic nematic liquid crystals (LCs) induce self-assembly on quantum dots (QDs) to form one-dimensional chains along the nematic director. Spatial ordering of QDs, achieved in the nematic LC matrix, can be controlled in a preferred direction on application of electric fields, gaining better self-assembly. Once the field goes off, the LC+QD system relaxes back to the original state, revealing the intrinsic dynamics. Due to the dielectric anisotropy of the system, this dynamic response can be captured by studying dielectric relaxation. The studied dynamic response reveals insights on the field-induced self-assembly mechanism and the stability of the LC+QD system.
