Tuning the structure and the properties of dithiafulvene metalla-assembled tweezers
Résumé
A M2L2 metalla-macrocycles contructed through coordination driven self-assembly from the Pd(dppf)OTf2 complex (dppf = 1,1′-Bis(diphenylphosphino)ferrocene) and an electron-rich 9-(1,3-dithiol-2-ylidene)fluorene bis-pyridyl ligand is depicted. This molecular tweezer exhibits a cavity able i) to promote dimerization upon oxidation and ii) to bind an electro-deficient substrate with a remarquable association constant. Those properties are compared with those of a previously described regioisomer.
