  An unexpected bidirectional molecular rotor from unidirectional molecular motor via a stereoselective enamine-imine tautomerization process

  摘要：

  Developing stereoselective synthetic method is very important to access chiral molecular devices. We herein demonstrate how a proton initiated stereoselective enamine-imine tautomerization converts a molecular motor into a simple rotor with high diastereoselectivity (>20:1 dr). NMR and X-ray crystallography were used to elucidate the structures of both the motor and rotor unambiguously. The activated motion of the rotor about its central single bond was studied from variable temperature NMR (293423 K) and DFT calculations provide evidence of the origin of diastereoselectivity of enamine-imine tautomerization as well as the rotor dynamics with barrier as high as 39.3 kcal/mol. Results from our work may benefit future design towards stereocontrolled and adaptive molecular machines. (C) 2020 Elsevier Ltd. All rights reserved.

  experimentally and theoretically that the ground state of compound 2 was a triplet state and that its singlet–triplet energy gap (ΔEST) was similar to that in fluorenylidene. The curved structure of compound 2 led to slightly better spin delocalization over the two adjacent aromatic rings than in planar systems, because of the unpaired spins on the σ and π orbitals. Synthetic application of the carbene

• Ultrafast Light-Driven Nanomotors Based on an Acridane Stator

  A series Of Molecular motors featuring a symmetrical acridane stator is reported. Photochemical and thermal isomerization experiments confirm that this stator, in combination with a thiopyran rotor, results in molecular rotary motion in which the rate-determining thermal helix inversion proceeds effectively only at temperatures above 373 K. The introduction of a cyclopentanylidene rotor unit results in a decrease in steric hindrance with respect to the stator, and as a consequence, a 10(12)-fold increase in the rate of thermal helix inversion is observed. Nanosecond transient absorption spectroscopy allows for the thermal processes to be followed accurately at ambient temperature. The rotary motor is shown to be able to operate at 0.5 MHz rotational frequencies Under optimal conditions.
