rotaxanen.

Brit.

/rə(ʊ)ˈtakseɪn/, U.S.

/roʊˈtækˌseɪn/

Origin: A borrowing from German. Etymon: German Rotaxan.

Etymology: < German Rotaxan (G. Schill & H. Zollenkopf 1967, in Nachrichten aus Chem. u. Technik 15 149/2; < classical Latin rota wheel (see rota n.) + ax- (in axis axis n.¹) + German -an -ane suffix²), with remodelling of the ending after -ane suffix².

Chemistry.

Any compound having a molecular structure in which a chain of atoms is threaded through a ring and, though not chemically bonded to the ring, is mechanically constrained in position by the ring's structure.

ΚΠ

1969 Chem. Abstr. 70 297/1 The name rotaxanes is suggested for newly synthesized aggregates consisting of a macrocycle and a chain with bulky end groups.

1998 Chem. in Brit. Oct. 33/2 The area of rotaxanes and catenanes—compounds that function as molecular switches.

2000 Nature 9 Nov. 153/1 Other approaches to linear motion rely on the use of rotaxanes—molecular rings threaded by strings—in which the position of the ring can be altered by electrochemical or photochemical means.
