Carboxy 9-dicyanomethylene nitrofluorene
Abstract
Abstract FLUORENES HAVE BEEN PREPARED CONTAINING A DIEYANOMETHYLENE GROUP IN THE 9 POSITION. IN ADDITION, THE 2,4,5, AND 7 POSITIONS CONTAIN CARBOXYL, CARBOXYL DERIVATIES, NITRO, OR HYDROGEN SUBSTITUENTS WITH THE PROVISO THAT THERE IS AT LEAST ONE CARBOXYL OR CARBOXYL DERIVATIVE IN ONE OF THESE POSITIONS. THE ELECTRON ACCEPTING PROPERTIES OF THESE COMPOUNDS AND DERIVED POLYMERS MAKE THEM USEFUL FOR TRAPS OR FILTERS FOR ELECTRON-RICH COMPOUNDS AND AS ULTRAVIOLET ABSORBERS. THESE FLUORENE ACCEPTOR MONOMERS AND DERIVED POLYMERS, READILY FORM CHARGE-TRANSFER COMPLEXES WITH A WIDE VARIETY OF P1 OR LEWIS BASES WHICH ARE USEFUL AS COLORING AGENTS, AS ELECTRICAL CONDUCTING MATERIALS AND AS LTRA-VIOLET ASBORBERS.
