Photolysis of Methyltrioctylammonium Tetrachloroferrate(III).

Formation of composite microspheres comprising a 2,2′-bipyridyl iron(ii/iii) complex and acrylamide by UV irradiation

“…This indicates that photo-reduction of the [FeCl 4 ] 2 ion is easier than the normal chemical reduction of free ferric ions. 10,11 Once the LMCT absorption of the [FeCl 4 ] 2 complex is excited, the complex tends to dissociate to give a chlorine radical and ferrous ion. 10 It is known that the transition 2 eBt 1 possesses the energy band gap 364 nm, being the smallest of all the three transitions given above.…”

Hence, it is only the possible transition by 355 nm UV irradiation.…”
