The focus of IUPAC | CHAINS 2023 is of course to present a solid base of inspiring scientific work by renowned chemists and young talent. But after a long day of plenary presentations, parallel and focus sessions, we also offer you fun activities to meet new people and broaden your horizon. 

All the details of this extra program can be found on, where you can sign up for the activities. Here, we give you a quick insight in what to expect. 

Welcome reception 

After the opening ceremony on Sunday evening, all attendees are invited to join the welcome reception at the World Forum to celebrate the start of the congress. 

Chemistry Pubquiz 

Do you think your knowledge about chemistry is up to scratch? Then sign up for the chemistry pubquiz on Monday evening, in the largest Irish Pub in The Hague: O’Caseys. You will be randomly assigned a team, and together you will try to solve the challenging questions that our hosts, professors Nathaniel Martin and Sander van Kasteren (Leiden University), will throw your way! 

Chemistry party 

After a day of cutting-edge science, you might want to join the Chemistry Party at Bleyenberg to blow off some steam on Tuesday evening. Meet up with old or new friends, relax at the Rooftop Bar, dance the night away or – if enough people sign up – even enjoy some karaoke! 

Technical Tours 

On Wednesday afternoon you will get some free time to explore the city or the nearby beach, but there are also Technical Tours which you can join. All these tours give you the chance to see more of the Netherlands but still learn something. You can for instance sign up to learn more about the science behind the restauration of Rembrandt’s painting De Nachtwacht; making cheese or brewing beer; or visit an interesting company or organisation.  

Gala Dinner at the Grote Kerk 

Right in the historic heart of the city centre of The Hague, you will find the iconic location for our gala dinner: the Grote Kerk. Together with the Binnenhof, the seat of the Dutch government, the Grote Kerk is one of the oldest buildings in The Hague. A perfect location for fine dining on Thursday evening. 

Exploring The Hague 

Perhaps you prefer to explore The Hague on your own. There is plenty to see! The Hague is home to several nice museums, is also close to the beach and to other interesting cities in The Netherlands. For suggestions on where to go, see
