Welcome
We are excited to announce the fourth edition of the International Conference on Excited State Aromaticity and Antiaromaticity (ICESAA-4), which will be held from January 8 to 11, 2026, at the Indian Institute of Science Education and Research Thiruvananthapuram (IISER-TVM), India. ICESAA-4, 2026 aims to bring together experts in theoretical and experimental chemistry to discuss the latest developments in the field of excited-state aromaticity and antiaromaticity. The conference will feature invited lectures, contributed talks, poster presentations and interactive discussions. Additionally, on the first day we will arrange a Winter School that will provide crucial background learnings in photochemistry, (anti)aromaticity and computational chemistry. We look forward to welcoming you to ICESAA-4 from January 8 to 11, 2026, at IISER Thiruvananthapuram, India, for another remarkable edition of this conference series!
