    • Crystal complexes of [C6AS6-+2H, Phen, 4·21H2O (1) and [C6AS 6, PPQ2+]3·31.5H2O (2) were prepared by the method of slow evaporation of solution, a) Preparation of complex 1: To an aqueous solution of C6AS (0.05 mmol, 20 mL) was added 6 equiv of Phen. Under stirring, 2 M HCl was dropped to adjust the pH to 1-2. After filtration, the filtrate was set aside to evaporate for 3 weeks. The colorless crystal that formed was then collected along with its mother liquor for the X-ray crystallographic analysis. 1H NMR (D 2O, δ, 8.99 (d, J, 4.8 Hz, 8H, Phen, 8.67 (d, J, 8.4 Hz, 8H, Phen, 7.93 (m, 16H, Phen, 7.23 (s, 12H, C6AS, 3.55 s, 12H, C6AS

    • The X-ray intensity data for 1 and 2 were collected on a Rigaku MM-007 rotating anode diffractometer equipped with a Saturn CCD Area Detector System using monochromated Mo-Kα radiation at T, 113(2) K. Data collection and reduction were performed by program of Crystalclear. The structures were solved by using the direct method and refined employing full-matrix least squares on F2 (CrystalStructure, SHELXTL-97, a) Crystal data for 1: C90H108N 8O45S6, M, 2214.20, triclinic, space group P1̄, a, 11.862(2) Å, b, 18.883(3) Å, c, 22.445(4) Å, α, 96.668(3)°, β, 94.163(3)°, γ, 95.226(2)°, V, 4954.9(14) Å3, Z, 2, Dc, 1.484 g cm -3, λ(Mo-Kα, 0.71070 Å, T, 113(2) K, F000, 2320, μ, 0.239 mm-1
    • 2 = 1.072. To satisfy charge balance, C6AS in 1 should possess two protonated sulfonate groups, which are acceptable given the pH of the reaction solution. The oxygen atoms of the sulfonate group (S5) are disordered over two positions. In addition, there are two very similar host-guest complex units in complex 1, so there are likewise two kinds of polymeric capsules. We give only the data of one, and the other is negligibly discussed in this text.

    • 2 = 1.381. The oxygen atoms of some sulfonate groups (S2 and S6) are disordered over two positions. Unfortunately, it was not possible to locate all hydrogen atoms from the Fourier difference map for this to be clarified. In addition, the R factor of crystal 2 is so high because the quality of crystal is not good enough and there are too many disordered water molecules.
