We would like to take this opportunity to express our sincere thanks for the support and contributions from all the outstanding authors. Without their dedication, this themed collection would not have been possible. We are also grateful to Dr Wenjun Liu, the deputy editor of Organic Chemistry Frontiers, as well as the whole journal team, for their efforts and professionalism.
