for the autoamplification of molecular chirality, wherein the amplification proceeds through the induction of supramolecular chirality, is presented. A solution of prochiral, ring‐open diarylethenes is doped with a small amount of their chiral, ring‐closed counterpart. The molecules co‐assemble into helical fibers through hydrogen bonding and the handedness of the fibers is biased by the chiral, ring‐closed
提出了分子手性自动扩增的新概念,其中扩增通过超分子手性的诱导而进行。前手性,开环二芳烃的溶液中掺杂有少量手性,闭环对应物。分子通过氢键共组装成螺旋状纤维,并且纤维的手性受到手性,闭环的二芳基乙烯的影响。开放的二芳基乙烯的光化学闭环产生了闭环产物,该产物富含模板对映体。
