New Organic Small Molecular Gelling Agent

The Organic Solids Key Lab in the Institute of Chemistry CAS has used the electrochemical activity and assembling feature of TTF (tetrathiafulvalene), developed a new organic small molecular gelling agent that can control the gelling process through oxidization and also conducted a detailed research on the gelling process, the gelling mechanism and the impact of the formation of charge transfer compounds and the oxidization on the gelling process. Besides, TTF units are also introduced into dinaphthalene molecules to form oxidization/reduction-controlled chiral molecular switch. The use of Rotaxane-containing TTF units in high-density information storage has also been discovered in collaboration with the Institute of Physics CAS.     The research on the chemical properties of TTF in recent years is focused on the ways to improve the electric conduction behavior of charge transfer compounds based on TTF derivatives. With the development of the research in super-molecular chemistry and molecular electronics, owing to the unique physical and chemical properties in electrochemical behavior, assembling feature and convenient derivatization TTF units have become functional structural units with greater importance.
