Notably, simple organiccages that exhibit guest-induced “breathing” and selective gas separation have been reported [29][39][40][41]. The reversible rearrangement of the

Among the remarkable architectures found in biological systems, those presenting a triple helical arrangement are of particular interest. Beside its classical double strand structure formed by
