Synthesis of amphiphilic chiral salen complexes and their conformational manipulation at the air–water interface

Abstract

A series of amphiphilic salen complexes, [L1a,bM] and [L2a,bM], were designed and synthesized. These complexes consist of two or four hydrophilic triethylene glycol (TEG) chains and the hydrophobic π-extended metallosalen...

Mechanical control of molecular machines at an air–water interface: manipulation of molecular pliers, paddles

“…Although there are few reported cases in which the conformation of binaphthyl molecules is controlled at the air – water interface, a change in the molecular arrangement has been observed for binaphthyl molecules with carboxylic acids as hydrophilic moieties upon compression [ 33 ]. In addition, S. Akine et al reported an attempt to control the molecular conformation of salen complexes with axial chirality at the air – water interface [ 31 ].…”
