T. Yatabe et Ge. Matsubayashi, INTERCALATION OF 2-SULFANYLPYRIDINE, 4-SULFANYLPYRIDINE, 2,2'-DITHIOBISPYRIDINE AND 4,4'-DITHIOBISPYRIDINE INTO VOPO4, AND GEL-V2O5 INTERLAYER SPACES, Journal of materials chemistry, 6(11), 1996, pp. 1849-1852
2-(2-Spy) and 4-sulfanylpyridine (4-Spy) have been inserted into the g
el-V2O5 interlayer space, accompanied by oxidative S-S coupling, to fo
rm intercalation compounds including mostly N-protonated 2,2'-(2,2'-py
SSpy) and 4,4'-dithiobipyridine (4,4'-pySSpy) moieties as a guest. 2,2
'-pySSpy and 4,4'-pySSpy were also intercalated into the gel-V2O5 inte
rlayer space to yield similar intercalation compounds. 2-Spy, 4-Spy an
d 4,4'-pySSpy formed no stable intercalation compounds with VOPO4 soli
ds, while 2,2'-pySSpy was inserted into the VOPO4 lattice to afford an
intercalation compound with fewer N-protonation sites. X-Ray diffract
ion patterns and X-ray photoelectron spectra of the intercalation comp
ounds are discussed.
