Chirality transcription and amplification by the formation of chiral [2]pseudorotaxanes by an achiral crown ether having the 2',2''-quaterphenyl group and chiral sec-ammonium ions are reported. It was revealed that the absolute configurations of the chiral sec-ammonium ions can be detected directly from the CD spectra of the chiral [2]pseudorotaxanes.
手性[2]伪轮烷的形成可实现对映体转录和放大，该[2]伪轮烷由具有 2',2''-四苯基基团的非手性冠醚和手性仲铵离子构成。研究表明，手性仲铵离子的绝对构型可以直接从手性[2]伪轮烷的 CD 光谱中检测出来。
