Next, we studied the effect of scrambling on the gas sorption properties for the family [Cu4(L)4-x(CH3L)x]. In this case both homoleptic cages show N2 uptake, although the sorption properties of the cage [Cu4(L)4] had not previously been reported. This homoleptic cage presents a Type I isotherm with rapid uptake of N2 at 77 K, reaching 88.8 cm 3 /g at P/P0 ≈ 0.06. At P/P0 ≈ 0.92, the uptake was of 123.7 cm 3 /g. The BET surface area calculated for [Cu4(L)4] is 367 m 2 /g (Fig. -75), compared to the previously reported BET surface area of 382 m 2 /g for all show increased uptake of N2 in the low pressure region P/P0 < 0.1 when compared to the homoleptic cages. Similarly, all show higher uptake at P/P0 ≈ 0.9, of 172.6, 217.2, and 201 cm 3 /g for [Cu4(L)3(CH3L)], [Cu4(L)2(CH3L)2], and [Cu4(L)(CH3L)3], respectively. Comparable increases in the adsorption of CO2 at 195 K are also found for the scrambled materials. This behaviour is reflected in higher BET surface areas for all of the scrambled cages when compared to the homoleptic materials, of 475, 566, and 559 m 2 /g for [Cu4(L)3(CH3L)],
