Gyroscope-like Molecules Consisting of PdX_2/PtX_2 Rotators Encased in Three-Spoke Stators:Synthesis via Alkene Metathesis,and Facile Substitution and Demetalation

摘要

Rotating objects are ubiquitous components of macroscopic machines,and most are encased in protective housings.These serve various functions,such as human safety or protection against other moving parts.Similarly,many types of molecular devices involve a rotating component,and the design of suprastructures that can shield them is receiving increasing attention.Two such cases would be molecular compasses and gyroscopes,which are composed of"rotators"and"stators".The ultimate goal would be stators that enclose the rotators in frictionless environments,both in solution and in the crystalline lattice.
