T. Fujinawa et al., UNUSUAL ELECTRICAL-PROPERTIES OF 1 1-CHARGE-TRANSFER COMPLEXES COMPOSED OF 1,6-DIAMINOPYRENE AND SOME TETRAHALO-P-BENZOQUINONES/, Synthetic metals, 86(1-3), 1997, pp. 1865-1866
Charge-transfer complexes of 1,6-diaminopyrene with p-chloranil (CHL),
p-bromanil (BRL), and 2,5-dibromo-3,6-dichloro-p-benzoquinone (DBDCQ)
have been prepared and subjected to structural and transport studies.
All of the 1:1 hydrogen-bonded complexes including some polymorphic c
rystals are found to have an almost neutral ground state. Some complex
es are found to have unusually low resistivities despite their mixed-s
tacked structures.
