Research Interests

We are interested in the development of novel pi-structures and synthesis of high performance conjugated materials for organic electronics and sensors.

 

Research Highlight

Ref.: Yuan, L.; Han, Y.; Tao, T.; Phan, H.; Chi, C.*, Formation of a Macrocycles-in-a-Macrocycle Superstructure with All-gauche Conformation by Reversible Radical Association. Angew. Chem. Int. Edit. 2018, 57, 9023-9027. 

An unprecedented macrocycles-in-a-macrocycle (MIM) superstructure was formed by reversible radical-radical association of a triphenylamine based monomer terminated with three dicyanomethyl radicals (1). The reaction yield is nearly quantitative and the obtained macrocycle (2) contains three small dimeric macrocycles. The six monomer molecules are linked by nine long dynamic covalent C-C bonds which all adopt a gauche conformation. Two enantiomers with left- / right-handed chirality exist in the single crystals of 2.
