文摘

The corrole鈥揷hromium(V)鈥搉itrido moiety is introduced as a uniquely sensitive EPR spin probe. We describe a series of corrole-centered poly(amidoamine) (PAMAM) dendrimers and the selective incorporation of the chromium(V)鈥搉itrido moiety. The chromium鈥揷orrole cores are reactive toward both neutral and charged reagents, and the accessibility of the dendrimer cores enables easy manipulation of the spin probe. The spin probe reveals a pronounced solvent dependence of the solution-phase structure of the dendrimers.
