Template confinement effects on discotic liquid-crystals (TEMPLDISCO)

该项目的总体目标是增加对纳米盘状液晶（DCLC）结构性质关系的基本认识。从基础研究和应用研究两方面来看，国际上对DCLC的兴趣日益浓厚。后者是由于DCLC作为有机和/或纳米电子学中的创新材料的潜在应用。将DCLC限制在模板（多孔硅，多孔铝）的纳米通道中可以作为该领域的突破口，有利于在大长度尺度上优化和调整柱状相的形成，并实现与其他固体界面的耦合。为了实现这一目标，将建立一个广泛的法国/德国联盟，将有机化学（合成定制DCLC）、无机化学（合成纳米多孔模板）和物理化学（表征）结合起来。此外，纳米限制DCLC的表征涉及广泛的方法，包括结构表征（量热法，双折射测量x射线，中子散射），分子迁移率的研究（介电弛豫，核磁共振，准弹性中子散射）和应用相关的研究，如电导率测量。除了讨论的要点外，该项目将有助于更好地理解一般的受限液体和软物质的物理化学。

The general aim of the project is to gain an essential increase of the basic knowledge on structureproperty relationships of nanoconfined Discotic Liquid Crystals (DCLC). There is a growing international interest on DCLC from both fundamental and applied point of research. The latter is due to a potential application of DCLC as innovative materials in organic and/or nanoelectronics. Confining DCLC into nanochannels of a template (porous silicon, porous aluminium) can serve as a break-through approach in this field which will be advantageous tp optimize and tune the formation of columnar phases over large length scales and realizing the coupling with other solid interfaces. To reach this aim a broad French/German consortium will be established which combines organic chemistry (synthesis of tailor made DCLC), inorganic chemistry (synthesis of nanoporous templates) with physical chemistry (characterization). Also the characterization of the nanoconfined DCLC interrelates a wide range of methods which includes structural characterization (Calorimetry, birefringence measurements X-ray, neutron scattering), the investigation of the molecular mobility (dielectric relaxation, NMR, quasielastic neutron scattering) and application related studies like conductivity measurements. Besides the points discussed, the project will contribute to a better understanding of physical chemistry of confined liquids and softmatter in general.
