Figure 4.15. N 2 sorption isotherms collected at 77 K for Ru-DEMOF samples 1a-1d, 2a-2c, 3a-3d,<br />
4a-4c. 1a-1d: DL is 5-OH-ip, incorporation amount is 8%, 20%, 32% and 37%, respectively; 2a-<br />
2c: DL is ip, incorporation amount is 15%,28% and 47%, respectively; 3a-3d: DL is 5-NH 2 -ip; 4a-<br />
4c: DL is 5-Br-ip, incorporation amount is 17%, 25% and 42%, respectively. Closed and open<br />
symbols represent the adsorption and desorption isotherms, respectively. Black circles – parent<br />
Ru-MOF; blue triangles – a samples of the respective series 1-4; dark cyan diamonds – b samples<br />
of the respective series 1-4; magenta squares – c samples of the respective series 1-4; dark yellow<br />
stars – d samples of the respective series 1-4.<br />
(1a-d, 2a-d, 3a-d and 4a-c) reveal type I isotherm without any hysteresis loop (Figure<br />
4.15), indicating that all Ru-DEMOFs are microporous materials. [228] In general, while<br />
comparing with the Brunauer-Emmett-Teller (BET) surface area (SBET) of the parent Ru-<br />
MOF (998 m 2 /g), one can consider Ru-DEMOFs being analogous when the value (SBET) is<br />
in/above the range of the parent one. In other words, the considerably high SBET of the<br />
discussed Ru-DEMOFs rules out substantial guests occlusion and pore blocking such as by<br />
non-reacted DLs, acetate or Ru/RuOx‐NPs. Interestingly, when 5-OH-ipH2 is used as DL,<br />
SBET of the Ru-DEMOFs gradually increases until 5-OH-ip is incorporated up to 32% (1c)
