The schematics of asymmetric 48Z_S_I(l, m, n) networks and the corresponding band structures. (a) Three-wing GNRs building block of asymmetric CFs and three width degrees of freedom, l, m, n, are considered. (b) and (c) m = n and m ≠ n asymmetric CFs, respectively. The orange and cyan sticks indicate the sp³ and sp² C atoms, respectively. (d) The band structures of (5, 3, 2), (5, 3, 3), (5, 4, 2), (5, 4, 3), (5, 4, 4), (5, 5, 2), (5, 5, 3), (5, 5, 4), and (5, 6, 6).^[81]
