CHARGE-TRANSFER COMPLEXES OF FLUORO-AND CYANO-SUBSTITUTED TETRACYANQUINODIMETHANS

摘要

Charge-transfer compounds of the formula Mn+(STCNQ )n(STCNQ DEG )b WHEREIN M is a cation of valance n+ when n is from 1 to 6, STCNQ is a tetracyanoquinolium substituted in the ring with at least two substitutents which can be fluorine or cyano, - denotes a negative charge, . denotes an unpaired electron, DEG indicates a neutral species, and b is a number from 0 to 3 including fractions, are useful as pigments in lacquers and for dying nylon, wool and silk.
