Journal of the American Chemical Society , 48 , In stages B and D the aryl can rotate with respect to the naphthalene with steric interactions preventing the aryl from passing the naphthalene.

The rotary cycle consists of four chemically induced steps which realize the conversion of one stage into the next. Steps 1 and 3 are asymmetric ring opening reactions which make use of a chiral reagent in order to control the direction of the rotation of the aryl.

Steps 2 and 4 consist of the deprotection of the phenol , followed by regioselective ring formation. The chemically driven rotary molecular motor by Feringa and co-workers.

Ben L. Feringa at the University of Groningen , The Netherlands reported the creation of a unidirectional molecular rotor. One cycle of unidirectional rotation takes 4 reaction steps. The first step is a low temperature endothermic photoisomerization of the trans P,P isomer 1 to the cis M,M 2 where P stands for the right-handed helix and M for the left-handed helix.

In this process, the two axial methyl groups are converted into two less sterically favorable equatorial methyl groups. Because the axial isomer is more stable than the equatorial isomer, reverse rotation is blocked. A second photoisomerization converts P,P cis 3 into M,M trans 4, again with accompanying formation of sterically unfavorable equatorial methyl groups.

Synthetic molecular motors: fluorene system A major hurdle to overcome is the long reaction time for complete rotation in these systems, which does not compare to rotation speeds displayed by motor proteins in biological systems. In the fastest system to date, with a fluorene lower half, the half-life of the thermal helix inversion is 0. In this molecule the slowest step in its rotation, the thermally induced helix-inversion, is believed to proceed much more quickly because the larger tert-butyl group makes the unstable isomer even less stable than when the methyl group is used.

This is because the unstable isomer is more destabilized than the transition state that leads to helix-inversion. The different behaviour of the two molecules is illustrated by the fact that the half-life time for the compound with a methyl group instead of a tert-butyl group is 3.
