The project is directed to the design, synthesis, structural and physico-chemical investigation of calixarene derivatives and their metal complexes for new molecular devices. Photo- and voltage-driven molecular devices will be developed, wherein the photo- and electro active species are separated by a calixarene platform. It is planned to synthesize calixarene derivatives with functional groups both on the upper and lower rims for the binding of two active species which are able to perform electron (energy) transfer processes and to investigate their configuration and conformation as well as their dynamic host-guest behaviour using modern methods of gradient 1D and 2D nuclear magnetic resonance (NMR). Transition metal ions are envisaged as photo- and electro-active species. The project is based on an exploitation of both rims of the calixarene matrix for inner- and an outer-sphere coordination of c/(/)-metal ions and their complexes. The outersphere coordination of metal complexes will be achieved by cooperative electrostatic and Van der Waals interactions between metal complexes and positively (negatively) charged rims of the calixarenes. The inner-sphere coordination will be governed by the modification of the lower rim of calixarenes with CN, OH, NH2, COOH moieties. In the course of the project it is intended to synthesize metat-calixarene-metal molecular systems with various lengths of the calixarene bridge and to investigate the influence of the metal to metal distance on the electron (energy) transfer between the metal ion centres. Both kinetic measurements and structural and dynamic NMR investigations will be applied for these purposes. The elongation of the calixarene matrix will be realized by variation of the lower rim substituents.

该项目针对新分子设备的钙甲烯衍生物及其金属复合物的设计，合成，结构和物理化学研究。将开发照片和电压驱动的分子设备，其中照片和电活性物种通过calixarene平台分开。它计划与上和下边缘上的官能团合成钙式衍生物，以结合两个活性物种，这些活性物质能够执行电子（能量）传输过程，并研究其配置和构象以及使用梯度1D和2D核磁共振（NMR）现代方法的动态宿主和构造行为。过渡金属离子被设想为光活性物种。该项目基于对Calixarene基质的两种边缘对C/（/） - 金属离子及其复合物的内部和外球配位的剥削。金属配合物的卵形配位将通过金属配合物之间的合作静电和范德华的相互作用来实现，并在卡利克利烯烯类的积极（负）带电的边缘。内球体协调将由CN，OH，NH2，COOH部分的钙钙齐烯烯的下边缘进行修饰。在项目的过程中，它旨在合成具有不同长度的calixarene桥的Metat--钙化 - 金属分子系统，并研究金属对金属距离对电子离子中心之间电子（能量）转移的影响。动力学测量以及结构和动态NMR研究都将用于这些目的。 Calixarene基质的伸长将通过下边缘取代基的变化来实现。
