title: A second-order nonlinear optical material with a hydrated homochiral helix obtained via spontaneous symmetric breaking crystallization from an achiral ligand.
abstract: A unique supramolecular helix assisted by solvent molecules (water and DMF) is obtained from an achiral flexible V-shaped ligand, and spontaneous symmetry breaking occurs in crystallization. Notably, the compound displays strong second-harmonic generation (SHG) response.
