Aftermovie IUPAC|CHAINS 2023


We are pleased to invite you to join us in the beautiful city The Hague for IUPAC|CHAINS2023 in August 2023. During the conference, themed ‘Connecting Chemical Worlds’, we bring together all disciplines of chemistry, a diverse audience of chemists from both academia and industry, and from all around the globe. Apart from plenary and invited lectures, the congress will include parallel sessions with oral presentations, focus sessions and poster presentations by junior and senior researchers.

The conference consists of several parts, namely the 52nd IUPAC General Assembly (18-25 August 2023) and the 49th IUPAC World Chemistry Congress combined with the 11th edition of CHAINS, the largest chemistry congress from the Netherlands (20-25 August 2023).

IUPAC|CHAINS2023 is organized by the Royal Netherlands Chemical Society (KNCV) and the Dutch Research Council (NWO). The IUPAC World Chemistry Congress is organized biennially with recent previous editions in Sao Paolo (2017), Paris (2019) and digitally in Montreal (2021). In 2023 we expect to welcome you on location in The Hague to meet each other in person.

We look forward to meeting you and your fellow chemists around the globe during 2023 in the Netherlands. Let’s connect!

With warm regards,

On behalf of the organizing committee,

Floris Rutjes
Chair Local Organizing Committee IUPAC|CHAINS2023
