Y. Kubo et al., A new biphenyl-20-crown-6-derived zinc(II) porphyrin dimer with a potentially heterotropic allostery, TETRAHEDR L, 40(33), 1999, pp. 6019-6023
Synthesis of a new bis-porphyrinic system coupled with biphenyl-20-crown-6
as an allosteric spacer, 1, is described; the incorporated rotatable biphen
yl unit is capable of regulating the porphyrin center-to-center distance by
an encapsulated metal ion in the crown-strapped cavity, so that the system
displayed a potentially heterotropic allostery at the binding stage with a
certain stereogenic alpha, omega-diamine guest, 2. (C) 1999 Elsevier Scien
