Abstract

A time resolved EPR (TR-EPR) spectrum of a radical–triplet pair (RTP) in the quartet excited state has been recorded by irradiating with visible laser light a solution of a [60]fullerene–crown ether conjugate and an ammonium aminoxyl radical; this is the first direct observation of a RTP in liquid solution for a stable host–guest complex between a macrocyclic ligand bearing a triplet precursor and an aminoxyl ammonium cation.
