The International Symposium on Nano & Supramolecular Chemistry (ISNSC) started in Busan, Korea, in October 2007 and has been held in Bangkok, Bali, Brisbane, Naples, Dresden, and Qingyang (China). This symposium series has become very successful, with approximately 200 to 250 participants from about 30 countries annually. The 12th ISNSC, canceled for three years due to the COVID-19 pandemic, was successfully resumed on July 23–25, 2023, in Chiang Mai, Thailand. The event’s main aim was to promote friendship and share recent scientific findings. The conference was attended by 230 scientists from 22 countries on all continents and featured 60 oral presentations and 93 posters across six sessions (Fig. 1). The event provided an excellent platform for participants to share their research experiences and innovative ideas on various interdisciplinary topics such as supramolecular chemistry, nano-science and technology, catalyst and material science, and engineering. It also offered an opportunity to conduct joint international research. Furthermore, students were given a chance to present their findings orally to a global audience through flash talk opportunities. A special session was held simultaneously to commemorate the late Dr. Jacques Vicens (1945–2020) [1,2,3], who worked at the CNRS (the French National Organization for Scientific Research) from 1981 to 2011.
