Abstract

Supramolecular system has received great attention in the fields of catalytic

magnetic

liquid crystal materials

and bio-organic chemistry in recent years. They are composed of monomeric units through non-covalent intermolecular interactions including intermolecular hydrogen bond and - stacking interaction. The result is that the energy of the molecular system is greatly reduced and the molecular structure becomes more stable

which leads to the emergence of new properties of the optics

electricity

magnetic

and biological activity. Till now

many supramolecular polymers with one-dimensional chain

two-dimensional layer or three-dimensional open framework structures have been reported. In this work

a 3-D supramolecular compound (C

)(C

) (BP1) was synthesized and characterized by elemental analysis

H NMR and single-crystal X-ray diffraction. In the crystal structure

multiform hydrogen bonds and - stacking interactions lead to a 3-D supramolecular compound. At room temperature in DMSO solution

the compound has purple fluorescent emission at 373 nm

when excited at excitation wavelength of 342 nm. Fluorescent emission of the compounds originates from

transitions in molecular. The crystal belongs to triclinic

space group
