Abstract
The novel hetero-stilbene derivatives were synthesized by the Wittig reaction between 2-formyl-4-pyrones and polysubstituted imidazole-based phosphonium salts in the presence of a base. The optical properties of the products were investigated via UV–Vis absorption and fluorescent emission spectroscopy in dilute ethanol solution. Electrochemical properties were also studied by the cyclic voltammetry in CH2Cl2 solutions. The phosphorus ylides obtained from α-halocarbonyls were also condensed with 2-formyl-4-pyrone to give two electrochemically inactive and non-emitting products.
期刊介绍：
The purpose of Polycyclic Aromatic Compounds is to provide an international and interdisciplinary forum for all aspects of research related to polycyclic aromatic compounds (PAC). Topics range from fundamental research in chemistry (including synthetic and theoretical chemistry) and physics (including astrophysics), as well as thermodynamics, spectroscopy, analytical methods, and biology to applied studies in environmental science, biochemistry, toxicology, and industry. Polycyclic Aromatic Compounds has an outstanding Editorial Board and offers a rapid and efficient peer review process, as well as a flexible open access policy.
