Modular Synthesis of Bipyridinium Oligomers and Corresponding Donor–Acceptor Oligorotaxanes with Crown Ethers
Abstract
Donor–acceptor [4]- and [6]rotaxanes have been prepared from bipyridinium (BIPY<sup>2+</sup>) oligomers and 1,5-dinaphtho[38]crown-10 (DN38C10) by a threading-followed-by-stoppering protocol employing click chemistry. An efficient, straightforward route to the BIPY<sup>2+</sup> oligomers has been developed that requires little to no chromatographic purification. Unlike most donor–acceptor oligorotaxanes that have been reported to date, 100% of the recognition sites on the dumbbells are occupied by rings- Text
