A New Type of Inclusion Compounds Composed of a Charge-Transfer Complex between Tetrakis(phenylethynyl)ethene and 2,4,7-Trinitrofluorenone

Abstract

Abstract Tetrakis(phenylethynyl)ethene and 2,4,7-trinitrofluorenone form a deep red charge-transfer complex which gives the inclusion compound with benzene. The crystal structure of the inclusion compound with benzene was determined. The inclusion compound is composed of new frameworks possessing cavities for recognition of benzene molecules. Other examples of the inclusion compound are described.
