摘要

Chart 1 1: n= l 2: n= 2 10a: n= l lob: n= 2 3: n= 3 4: n= 4 1Oc: n= 3 10d: n= 4 rings of diphenoquinone, that is 2, 5-bis (4-oxo-2, 5-cyclo-hexadien-1-ylidene)-2, 5- dihydrothiophene and its oligodihydrothiophene analogues. In such a system, amphotericity can be enhanced by the conjugated sp2 carbon chain and the heteroaromatic stabilization of the corresponding radical ions and divalent ions created through the redox processes. ...
