“…12 MOFs composed of 1D pore structures (nanochannels) are excellent candidates for aligning guest molecules; indeed, incorporating molecules within their pore networks has been shown to enhance the mechanical, electrical and optical properties of the frameworks. [13][14][15][16][17][18][19][20][21][22][23][24] Examples of MOFs that possess 1D nanochannels, crystallographically oriented along the c axis, include pillarlayered M 2 (linker) 2 DABCO MOFs (linker: 1,4-benzenedicarboxylate (BDC), 1,4-naphthalenedicarboxylate (1,4-NDC), 2,6naphthalenedicarboxylate (2,6-NDC), and 4,4 0 -biphenyldicarboxylate (BPDC); DABCO: 1,4-diazabicyclo[2.2.2]octane, M ¼ Cu, Zn) ( Fig. 1a).…”
