Résumé Ardashīr I, in the third century claimed to be the king of the Iranians, and by the time of Shapur I the realm was known as Ērānšahr , i.e., the “Empire of the Iranians.” During the Sasanian period, not only the idea of Iran took form, but its …

Abstract Activation of small molecules by donor-acceptor systems is conceptually important as many catalytic processes rely on the synergistic action of electron-rich and -poor sites to cooperatively activate and cleave bonds. This pertains to both the …
