Making matter from flights of fancy
At one stage, Hansjörg Grützmacher, a professor of inorganic chemistry at ETH Zurich, wanted to become an artist. Now, as a chemist, he sees a certain affinity between the two with which ideas can be realised.
What do you regard as chemistry’s greatest
achievement or most important discovery?
Every discovery is valuable at the time; it doesn’t
necessarily get recognised, that’s all. The greatest achievement of those
involved with chemistry – chemists, in other words – is that they have
succeeded in transforming a secret science into a key natural science.
What do you focus on in your research and what aspects
of it are evident or usable in everyday life?
We’re
concerned with researching efficient synthesis methods for special chemicals.
One milestone here is definitely the significantly improved synthesis of a
photo-initiator at ETH Zurich that is now produced at BASF Switzerland
(formerly CIBA) using this method. The initiator is used in many coating
processes, such as car paint, CDs or DVDs, not to mention in medicine, such as for
hardening synthetic dental fillings.
What fascinated you about chemistry? Why did
you want to become a chemist?
Turning ideas, “flights of fancy”, into matter, the
“products”. The only other people who do so in a similar way are artists – which
is what I originally wanted to study.
Which areas of chemistry will become
particularly important in future and why?
The biggest challenge will be to find reliable and
efficient systems that can provide, store and consume energy. Humankind has
always fought wars over resources so, unless we can make a breakthrough here,
conflicts across cultural borders are inevitable. It’s also a way of handling
our raw materials more sparingly, of course, but it can’t be the one we want.
And the global level of education is too low to deal with this threat
peacefully.
What concept from chemistry should everyone
know by the end of the International Year of Chemistry and why?
Atom;
molecule; matter. The understanding of one determines the understanding of the
other. And it would be good if people realised and understood that there’s
something new and unforeseen to be discovered for each of these concepts.
Science is dynamic and needs widespread public acceptance and support.
About the person
Fifty-two-year-old Hansjörg Grützmacher has been a full professor since 2001 and currently heads the Laboratory of Inorganic Chemistry at ETH Zurich. His main research interests include organo-metallic chemistry and chemistry of the main group elements specialising in novel bond systems.
