Encapsulated di-chloro-ethane-mediated inter-locked supra-molecular polymeric assembly of A1/A2-dihydroxy-oct-yloxy pillar[5]arene 1,2-di-chloro-ethane monosolvate.

Crystals of 1-(1,4-dihy-droxy)-2,3,4,5-(1,4-dioct-yloxy)-pillar[5]arene, C99H158O10·C2H4Cl2, were grown from a 1,2-dicholoro-ethane/n-hexane solvent system. In the crystal, the encapsulated 1,2-di-chloro-ethane solvent is stabilized by C-H⋯π inter-actions and mediates the formation of an inter-locked supra-molecular polymer via C-H⋯Cl inter-actions.

Chemical context

Supra­molecular polymers constructed by reversible non-covalent inter­actions such as hydrogen bonds, metal–ligand inter­actions, host–guest inter­actions, π–π inter­actions and van der Waals forces have gained considerable inter­est for their intriguing properties of recycling and responsiveness to external stimuli (Raghupathi et al., 2014 ▸; Takashima et al., 2017 ▸). Pillararenes are unique three-dimensional macrocyclic compounds which possess symmetric rigid structures and are easy to functionalize with various substituents (Ogoshi et al., 2008 ▸; Al-Azemi et al., 2017 ▸). They exhibit outstanding abilities to selectively bind different kinds of guest mol­ecules and thus are excellent host mol­ecules for guest encapsulation and mol­ecular recognition. Their unique structural features also enable them to exhibit inter­esting self-assembling characteristics, which make them potential candidates for use in fabricating functional materials in supra­molecular systems and nanotechnology. The construction of pillararene-based supra­molecular assemblies is very inter­esting because it raises the possibility of using these macrocycles for many important functional materials, which include enzyme models, field-effect transistors, gas sensors or photovoltaic cells (Han et al., 2015 ▸; Pan & Xue, 2013 ▸; Hu et al., 2016 ▸; Zhang et al., 2018 ▸).

Supra­molecular motifs such as hydrogen bonding or host–guest inter­actions can be employed to promote the self-assembly of pillararene analogues. The introduction of appropriate peripheral functionalization at the macrocycle will give rise to numerous features that also allow their organization at a supra­molecular level (Xue et al., 2012 ▸). The characteristics of the encapsulated guest mol­ecules can also be utilized to tune the supra­molecular nature of these macromolecules. The present work discusses the crystal structure of a pillararene system, Pil-OctOH·C, which possesses two hy­droxy groups at the macrocyclic periphery. The remaining apical sites on the pillararene are functionalized with long n-oct­yloxy substituents. The role of the guest mol­ecule in the formation of an inter­locked supra­molecular polymer via various supra­molecular inter­actions is also described.

Structural commentary

Fig. 1 ▸ shows the structure of the title A1/A2-dihy­droxy-oct­yloxy-pillar[5]arene (Pil-OctOH). The asymmetric unit contains half of the mol­ecule and the whole structure is generated by twofold rotation symmetry (symmetry operation: −x + 1, y, −z + ). The 1,2 di­chloro­ethane solvent is encapsulated within the pillararene cavity. The basic pillar[5]arene macrocycle is a penta­gon with an average corner-to-centroid distance of 4.99 Å. As a result of the presence of eight linear n-oct­yloxy chains at its apical positions, this novel pillararene could be considered to be a long cylindrical-shaped functional mol­ecule where the long tail ends are hydro­phobic in nature. Additionally, the presence of hy­droxy groups at two apical positions provides a hydro­philic pocket in the vicinity of the pillararene macrocycle. The hydroxyl groups are observed to be engaged in intra­molecular hydrogen bonds with the oxygen atoms of the adjacent oct­yl­oxy moieties via O—H⋯O inter­actions (Fig. 1 ▸ and Table 1 ▸).

Supra­molecular features

In the title macrocyclic compound, the encapsulated 1,2-di­chloro­ethane solvent is stabilized inside the cavity by C—H⋯π inter­actions with the pillararene aromatic ring (Table 2 ▸). Inter­estingly, the guest 1,2-di­chloro­ethane facilitates the formation of a supra­molecular inter­locked network through efficient C—H⋯Cl inter­actions (Fig. 2 ▸ and Table 1 ▸), which form chains along the b-axis direction. Additional stabilization of these chains is attained by dimer formation via weak C—H⋯C inter­actions between pillararene octyl chains (Fig. 2 ▸ and Table 2 ▸). Although the A1/A2 dihy­droxy groups on the pillararene rim play no part in the formation of the supra­molecular assembly, their small size provides an opening which enables access to the encapsulated guest mol­ecule. The pillararene mol­ecule in each chain inter­acts with neighboring pillararenes of adjacent chains by C—H⋯C and C—H⋯π inter­actions, as given in Fig. 3 ▸ and Table 2 ▸.

Synthesis and crystallization

The synthesis of 1-(1,4-dihy­droxy)-2,3,4,5 (1,4-dioct­yloxy)-pillar[5]arene (Pil-OctOH) has been reported earlier (Al-Azemi et al., 2018 ▸). Good quality single crystals of this compound were obtained by dissolving the pillararene (25 mg) in 1,2-di­chloro­ethane (0.5 mL) in a small vial and allowing solvent diffusion by keeping this solution in a larger vial containing n-hexane (5 ml). Within three days, crystals of the title compound of a suitable size for diffraction analysis had formed.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 3 ▸. The OH hydrogen atoms were located in the electron density map. All other hydrogen atoms were placed at calculated positions and refined using a riding model with C—H = 0.95–0.99 Å and U iso(H) = 1.2 or 1.5U eq(C).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
