An optical data storage medium, comprising; (a) an amorphous matrix; and (b) guest molecules dispersed in the amorphous matrix, the guest molecules consisting essentially of electron donors and electron acceptors which are in a solid state at room temperature, the optical data storage medium having an inhomogeneously broadened absorption band due to a distribution of local environments around the guest molecules dispersed in the amorphous matrix, such that the optical data storage medium is capable of storing at least two bits of data in a frequency domain by virtue of an irreversible multiphotonic electron transfer reaction consisting of more than one photon process, in which at least one electron is transferred from the electron donors to the electron acceptors.
