Face and edge directed self-assembly of Pd₁₂ tetrahedral nano-cages and their self-sorting.

ABSTRACT: Reactions of a cis-blocked Pd(ii) 90° acceptor [cis-(tmeda)Pd(NO₃)₂] (M) with 1,4-di(1H-tetrazol-5-yl)benzene (H₂L¹ ) and [1,3,5-tri(1H-tetrazol-5-yl)benzene] (H₃L² ) in 1 : 1 and 3 : 2 molar ratios respectively, yielded soft metallogels G1 and G2 [tmeda = N,N,N',N'-tetramethylethane-1,2-diamine]. Post-metalation of the gels G1 and G2 with M yielded highly water-soluble edge and face directed self-assembled Pd₁₂ tetrahedral nano-cages T1 and T2, respectively. Such facile conversion of Pd(ii) gels to discrete tetrahedral metallocages is unprecedented. Moreover, distinct self-sorting of these
