X-ray crystal structures, solid-state photoluminescence, and Kurtz-Perry powder second harmonic generation (SHG) efficiencies of two novel noncentrosymmetric polymeric adducts of CuI with 4-acetylpyridine, a double-stranded "stair" and a single-stranded "chain", are reported, the latter being a rare example of a [CuX(L)2]n motif (X = halide, L = pseudoaromatic η1-nitrogen donor ligand). In a series of structurally related noncentrosymmetric [CuX(L)]n chains and stairs, the powder SHG responses are interpreted in terms of both structural motifs (chains showing definitely greater efficiency than stairs) and "intrastrand" charge transfers involving the bridging halides.

Abstract

X-ray crystal structures, solid-state photoluminescence, and Kurtz-Perry powder second harmonic generation (SHG) efficiencies of two novel noncentrosymmetric polymeric adducts of CuI with 4-acetylpyridine, a double-stranded "stair" and a single-stranded "chain", are reported, the latter being a rare example of a [CuX(L)2]n motif (X = halide, L = pseudoaromatic η1-nitrogen donor ligand). In a series of structurally related noncentrosymmetric [CuX(L)]n chains and stairs, the powder SHG responses are interpreted in terms of both structural motifs (chains showing definitely greater efficiency than stairs) and "intrastrand" charge transfers involving the bridging halides.
