Abstract

Electronic absorption, polarized absorption and fluorescence spectra were measured to clarify the electronic structures and the nature of elect Tonictransitions of [Nd(acac)(terpy)(NO3)(2)] and [Pr(acac)(terpy)(NO3)(2)H2O]. It is found for both complexes that the nn; transition is localized on theterpyridine moiety whereas the nn; transition can be assigned to the intramolecular CT transition from the terpyridine moiety (pi HOMO) to the acetylacetone (pi LUMO). [Nd(acac)(terpy)(NO3)(2)] (or [Pr(acac)(terpy)(NO3)(2)N2O]) fluoresces from the upper excited state localized on the terpyridine moiety. This emission phenomenon is considered in detail because emissions from higher excited states are rarely observed. (C) 2001 Elsevier Science B.V. All rights reserved.
