The hydrogen-bonded organic framework (
PFC-32), constructed by
tetrahydroxyquinone (THQN) and diethylamine (DEA), was readily prepared via
hydrothermal synthesis in DEF (N,N-diethylformamide).
PFC-32 was characterized by PXRD, IR, UV-Vis, TGA and photoluminescence
(PL). Single crystal analysis reveals that
PFC-32 shows a three-dimensional (3D) framework, where the THQN anions are coplanar and
separated by DEA cations.
PFC-32 displays intrinsic photoluminescence property owing to the alleviation of the aggregation-caused
quenching (ACQ) effect caused by
π-
π stacking.
