2 Introduction Crown Ether Conjugated Polymer Rigid ring Flexible side groups Shape-Persistent Macrocycles Introduction The side group orientation determines the properties of the macrocycles

3 Properties of the Shape-Persistent Macrocycles 1. Aromatic corner pieces interrupt the conjugation. 2. Solubility dramatically reduce. 3. High melting points. Synthetic Strategies to Shape-Persistent Macrocycles Chem.Commun. 2003,

4 Synthetic Strategies to Shape-Persistent Macrocycles One-step cyclization High-dilution conditions!! The yields too low!! Difficult to purify!! H. A. Staab et al. Synthesis, 1974, 424 Synthetic Strategies to Shape-Persistent Macrocycles Intramolecular Cyclization Moderately high yield (ca %) Control the size and functional group. Time-consuming on the precursor J. S. Moore, et al. Angew. Chem. Int. Ed. Engl., 1992, 31, 922.

5 Synthetic Strategies to Shape-Persistent Macrocycles Bimolecular Coupling Cyclization Pseudo-high-dilution conditions (< mm) The procedure more time-efficient. The strategy can applicable to a verity of coulping reactions Low yields than intramolecular coulping S. Höger, et al. Angew. Chem. Int. Ed. Engl., 1995, 34, Synthetic Strategies to Shape-Persistent Macrocycles Using non-covalent templates Sanders, et al. J. Am. Chem. Soc., 1995, 117, 6611.

6 Synthetic Strategies to Shape-Persistent Macrocycles Covalent Templated Cyclization The size can be controlled by the template. Good yield! Needed to attach and cleave the template.
