Achieving Adaptive Aromaticity in Cyclo[10]carbon by Screening Cyclo[n]carbon (n = 8‐24)

Discovery of species with adaptive aromaticity (being aromatic in both the lowest singlet and triplet states) is particularly challenging as cyclic species are generally aromatic either in the ground state or in the excited state only according to Hückel’s and Baird’s rules.
