Abstract

1,3-Alternate calix[4]arene with para-phenylene spacers connecting nitroxide monoradicals and high-spin (S = 1) diradicals provides tetraradical and octaradical scaffolds that possess conformations with slow electron spin relaxation rates (1/T1). Such scaffolds may facilitate tuning of relaxation rates that are more favorable for MRI or DNP applications.
