Gigantic Porphyrinic Cages

Chiral Self‐sorting of Giant Cubic [8+12] Salicylimine Cage Compounds

“…The cavity of ( P , M )‐ 4 has an inner diameter of 3.3 nm (measured between the apical carbon atoms of two opposite TBTQ‐units) and thus the cube has a void volume of about 6.9 nm 3 . With these cage dimensions, ( P , M )‐ 4 is one of the largest purely organic cages reported that has been characterized by X‐ray diffraction; similar in size to the boronic ester cage of our group ( d in =3.1 nm), [33] but smaller than the recently published resorcinarene based cages from the Yuan group ( d in =3.9 nm) [34] and the giant porphyrinic cages from Kimoon Kim and co‐workers ( d in =4.3 nm) [35] . The rectangular cage window is exceptionally large with a size of approx.…”

“…The rectangular cage window is exceptionally large with a size of approx. 2.0×1.2 nm (measured between opposite aryl rings) and a diameter of 2.3 nm (Figure 6 b) and only the giant porphyrinic cages from Kimoon Kim and co‐workers have slightly larger cage windows of approximately 1.8×1.5 nm [35] . The molecules pack through weak van der Waals interactions between the edges of adjacent cage molecules involving the propyl‐chains and apical methyl‐groups of the TBTQ‐units of one cage and the aryl rings and phenolic OH groups of the other cage (Figure 6 c).…”

Crystals of the meso cage compound (P,M)-4 grown from dichloromethane were isomorphic to those grown from CDCl 3 with the exception that the cell parameters are slightly different (for details,see Supporting Information).…”
