Influence of heteroligand complexation on the thermal, photoluminescent, and film-forming properties of some aromatic terbium(III) carboxylates

Abstract : With homoligand TbL3 and heteroligand complexes TbL3(Q)n (HL = HSal (salicylic acid) and HPA (2-anilinobenzoic acid); Q = TPPO (triphenylphosphine oxide) and TOPO (tri(n-octyl)phosphine oxide); n = 1 or 2) as examples, it was shown that heteroligand complexation affects not only the thermal and photoluminescent properties but also the quality of films obtained by centrifugation: the root-mean-square roughness changes in the order TbL3Q > TbL3(Q)2 ≈ TbL3. This is due to different association degrees of the complexes in solution, which was confirmed by MALDI-TOF MS data.
