Abstract

Abstract : The first transition-metal nitro complex that exhibits optically reversible room-temperature photoswitchability with notable nitro-to-nitrito conversion of ca. 55% is reported. Abstract : A simple trinitro cobalt complex [Co(3, 3′-diamino- N -methylpropanediamine)(NO2 )3 ] was proven to be photoswitchable at room temperature as the Pca 21 polymorph with the maximum nitro-to-nitrito conversion reaching ca. 55%. Solid-state IR, UV-vis and XRD indicate that the transformation can be triggered optically in both ways via 470 nm and 570–660 nm LED light, respectively.
