| Summary: | 碩士 === 淡江大學 === 化學學系 === 82 === Simple and complex alkylammonium salts of electron acceptors
Qimnt(2,2''-(4,8-dihydro-4,8-dioxo-[1,2-d:4,5-d''] -bis[1,3]
dithiolebenzo-2,6-diylidene)-bispropanedinitrile were
electrocrystallized by reaction of the electron acce- ptor with
R4NBr ( R= tetramethylammonium,tetraethylammonium
,tetrapropylammonium, tetrabutylammonium ) in acetonitrile.
Physical properties of these crystals were also measured,
including infrared spectra , ultraviolet-visible spectra ,
SQUID magnetic susceptibilities , and D C-conductivities
measurements. The crystals and molecular structure of [tet-
ramethylammonium][Qimnt]2 and [tetraethylammonium][Qimnt]2 have
been determined by the single-crystal X-ray diffraction
analysis. Both complexs are segregated stacked and dimer
structure. All the salts behave as semi-conductor,the D C-
conductivities range from -3 order to -8 order。
