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 52^nd IUPAC General Assembly (18-25 August 2023) and the 49^th IUPAC World Chemistry Congress combined with the 11^th 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.
