Fig. 3: The ordered complexity of COF-305 and sequences of struts.
From: Encoding ordered structural complexity to covalent organic frameworks
a The primitive interpenetration cell (PIC) of COF-305 consists of nine adamantane cages in a column, each incorporating twelve struts. The diamondoid network of COF-305 can then be generated from the PIC through translational symmetry operations. b Five diamondoid frameworks offset by translation vector [0 1/2 1/2] interpenetrate to give COF-305. c The key feature of ordered complexity in COF-305 is that the nine different struts show specific sequences along the b-axis.
