X-band echo-detected electron paramagnetic resonance (ED EPR) spectra of triplet state of fullerene C(70) generated by continuous light illumination were found to correspond below 30K to a non-equilibrium electron spin polarization. Above 30K spectra are characteristic of Boltzmann equilibrium. Spectra

Under the direction of intramolecular three-center hydrogen bonding, two cyclotriveratrylene (CTV)-based capsules are assembled quantitatively from C(3)-symmetric CTV precursors by forming three imine bonds from arylamide-derived foldamer segments. (1)H and (13)C NMR and UV/vis experiments reveal that the capsules strongly
