A novel approach was developed for the generation of white-light emission from isostructural mixed Ln3+-4-(dipyridin-2-yl)aminobenzoate coordination polymers [Ln3+ = Eu3+ (1), Tb3+ (2), and Gd3+ (3)] by tuning the excitation wavelength.

Using mono- and 1,n′-disubstituted ferrocenecarboxylicacid, the aminoethylglycine (aeg) derivatives Fe[C5H4-CO-aeg-OtBu][C5H5] (1) and Fe[C5H4-CO-aeg-OtBu]2 (2) have been synthesized. Complexes 1 and 2 are further reacted to substitute the aeg with the nitrogen-containing ligands dpa-ph-CO2H or py-AcOH to yield complexes 3–6. Each of these is treated with Re(CO)5Cl to assemble heterometallic structures

(dpa), dpa-CH2CO2H (1) and dpa-PhCO2H (2), are described. Ligands 1 and 2 are successfully coupled to the amino acid phenylalanine, yielding the derivatives 4 and 6, respectively. Four CuII(dpa)2 complexes, [Cu(dpa-CH2CO2tBu)2(NO3)2] (3Cu), [Cu(dpa-CH2CO-PheOMe)2(H2O)2](NO3)2·2MeOH (4Cu), [Cu(dpa-PhCO2Me)2 (MeOH)2](ClO4)2 (5Cu) and [Cu(dpa-PhCO-PheOMe)2(ClO4)2] (6Cu) have been prepared and characterized
