Host : Assoc Prof John Yip Hon Kay
About the Speaker
Professor Gao Song got his BS and PhD in chemistry at Peking
University (PKU) in 1985 and 1991, and then worked at PKU till
now. He was a Humboldt Research Fellow in TH Aachen from
1995 to 1997. He has been Cheung Kong Professor in College of
Chemistry and Molecular Engineering at Peking University since
2002, and served as dean of this college in 2006-2010. He is now
deputy director of Beijing National Laboratory for Molecular
Sciences. He received State Natural Science Award (the 2nd
Grade) in 2006 because of his contribution in magnetic ordered
coordination polymers and molecular nanomagnets. He was
elected as member of Chinese Academy of Sciences in 2007. In the same year, he
became a Fellow of the Royal Society of Chemistry (UK). He is member of Editorial
Advisory Board for Chem. Soc. Rev., Chemical Science, and Inorganic Chemistry etc.,
and Associate Editor of CrystEngComm. Professor Gao Song and his collaborators
published more than 300 papers with h-index 51. He is the chairman of the 12th
International Conference on Molecule-based Magnets held in Beijing in 2010. His
research interests are magnetic ordered coordination polymers, molecular
nanomagnets, molecular and crystal engineering, and multifunctional molecular
materials.
Abstract
This talk will review the progress in the filed of multifunctional magnetic
molecular materials, such as ferromagnetic conductors, photo and piezo
switching magnets, chiral magnets, and multiferroics. Some recent results from
our lab on new ferroelectric magnetic metal-organic frameworks (MOF), and
new iron(II) spin crossover (SCO) compounds with N4O2 coordination sphere,
will be presented.

Abstract
Single-molecule magnets (SMMs) have been received great attention for their
unique properties since 1990s, such as very slow relaxation and quantum
tunneling of magnetization, which offer the opportunity of potential application in
information storage and quantum computation at molecular level. Recently we
are going to explore the smallest molecular entity with isolated single spin center
showing SMM or SMM-like behavior, single-ion magnets, based on the previous
work. Some recent results on Dy(III) and Er(III) based mononuclear molecules
and their SMM behaviors will be presented.

Abstract
Single-chain magnets (SCM) are a novel class of molecular magnetic materials exhibiting
slow magnetic relaxation, which arises from large uniaxial type magnetic anisotropy,
strong intrachain and very weak or negligible interchain magnetic interactions. Although
more than 20 examples of SCM have been reported, the controlled synthesis of SCMis still
a challenge. In this seminar, I will review the three strategies for the construction of SCM,
highlight typical examples, discuss the role of intrachain and interchain interactions on
the overall magnetic behavior of SCM as well as how to control or tune these interactions.
For each strategy we present the advantages/shortcoming and then point out the main
directions that remain to be developed in the field.
