Perylene diimide derivative via ionic self-assembly: helical supramolecular structure and selective detection of ATP

Abstract

A novel perylene diimide material (perylene diimide tetracid- dihexadecyldimethylammonium bromide, PDTA-DHAB) with unique hierarchical structure was designed and prepared by ionic self-assembly (ISA) method. The self-assembly behavior and aggregated structure of the complex were then studied by a variety of techniques such as UV-Vis absorption spectra, differential scanning calorimetry, and two-dimensional X-ray diffraction. With the presence of a rigid linkage, the complex can self-assemble into highly ordered helical columns which further pack into a monoclinic crystalline lattice with dimensions of a = 4.02 nm, b =3.40 nm, c = 2.90 nm, α = β = 90º, γ = 92º. During heating, the helical supramolecular structure was destroyed and transformed to a lamellar liquid crystalline phase. Furthermore, PDTA-DHAB system can exhibit sensitivity and selectivity to adenosine triphosphate (ATP). These results will provide insight into the rational design of functional materials with helical supramolecular structure and fluorescence detection ability through ISA method.
