Crystal Structures and Solid-State Optical Properties of Supramolecular Organic Fluorophore Composed of 1D Columnar Network Structure Consisting of Fluorescent 2-Naphthalenecarboxylic Acid

Supramolecular organic fluorophores composed of a one-dimensional (1D) column network structure were successfully developed using three types of 1-phenylethylamine derivatives as amine molecules and 2-naphthalenecarboxylic acid as a fluorescent acid molecule. These supramolecular organic fluorophores are formed by changing the style of the 1D columnar network structure and its packing arrangement, and their solid-state fluorescence properties are tuned according to their changes.
