Dear Friends and Colleagues

We are pleased to invite you to attend the 4^th International Symposium on Halogen Bonding (ISXB-4) to be held in Stellenbosch, South Africa, 23-27 March 2020.

As with the previous symposia in this series, the aim of ISXB-4 is to bring together scientists from a variety of disciplines, but with a common interest in the halogen bond and related interactions. The symposium will cover both experimental and theoretical aspects of a broad range of fields such as medicinal chemistry, chemical biology, materials science and industrial applications through keynote addresses, contributed presentations and posters. Following on from the previous meetings there will be a focus on young scientists, with special sessions for emerging investigators and for undergraduates and high-school learners.

ISXB-4 will be held on the picturesque campus of Stellenbosch University, which is situated in the heart of the historical town of Stellenbosch, a popular tourist destination surrounded by mountains and vineyards. It is well-known for the excellent locally-produced wine, good food and a range of modern art galleries. Also nearby is Cape Town, a vibrant, cosmopolitan city which is world renowned for the iconic Table Mountain and beautiful beaches with prolific sea life, including penguins.

We look forward to welcoming you to Stellenbosch in 2020!

Best wishes,

Catharine Esterhuysen (on behalf of the ISXB-4 Organising Committee)
