M. Takase et M. Inouye, Ferrocene-modified bis(spiropyridopyran)s as synthetic signaling receptorsfor guanine-guanine dinucleoside derivatives, CHEM COMMUN, (23), 2001, pp. 2432-2433
A ferrocene-linked bis(spiropyridopyran) was designed and synthesized, that
recognized guanine-guanine dinucleoside derivatives via complementary hydr
ogen bonds in CH2Cl2, resulting in the isomerization of the colorless spiro
pyridopyran as self-indicating receptors.
