Abstract:
1,4‐Butylidenedipyridinium (C 4 DP 2+ ) and 1,10‐decylidenedipyridinium (C 10 DP 2+ ) cationic guests form highly stable 1:1 inclusion complexes in aqueous solution with a cucurbit[8]uril (Q[8] ) host. Single‐crystal structure analysis of the inclusion complexes revealed that the alkyl chain of the C n DP 2+ ( n = 4, 10) cationic guest adopts an unconventional contorted conformation, which is attributed to favorable host–guest interactions (including charge–dipole and hydrophobic interactions) when bound within the cavity of the Q[8] host. Moreover, their crystal structures suggest that the alkyl chain and the aromatic group can be encapsulated into the Q[8] host simultaneously, and the alkyl chain is more favorably encapsulated into the Q[8] host than the aromatic group.
