This program's main objective is to develop strategies and methods to control the behavior and function of molecules at the supramolecular level via self-assembly. To be able to orchestrate the organization of matter at the nanoscale from the ground up (i.e. supramolecular synthesis), we will (a) synthesize molecules that are capable of undergoing a hierarchical self-assembly process into nanotubular architectures with predefined dimensions, physical, chemical, and biological properties, (b) establish their self-assembly with a variety of spectroscopic, imaging, and modeling tools, and (c) investigate their chemical and physical properties. In particular we have over the past five years established that carefully designed heterobicyclic motifs featuring specific sets of hydrogen bond donors and acceptors in pre-defined planes self-assemble into six-membered supermacrocycles (rosettes) maintained by 18 or 36 H-bonds, which then stack to form stable rosette nanotubes (RNTs) with unprecedented chemical, physical and biological properties.

该计划的主要目标是开发策略和方法，通过自组装在超分子水平上控制分子的行为和功能。 为了能够在纳米尺度上从头开始组织物质（即超分子合成），我们将（a）合成能够经历分级自组装过程的分子，使其成为具有预定尺寸、物理、化学和生物学性质的纳米管结构，（B）用各种光谱、成像和建模工具建立它们的自组装，及（c）研究其化学及物理性质。特别是在过去的五年中，我们已经确定，精心设计的杂双环基序具有预定义平面中的特定氢键供体和受体组，自组装成由18或36个H-键维持的六元超大环（RONTs），然后堆叠形成具有前所未有的化学，物理和生物学特性的稳定的玫瑰花状纳米管（RNT）。
