This manuscript addresses the synthesis, structural characterization and optical properties of a 1D coordination polymer(CPs) and 2D and 3D Metal-Organic Frameworks (MOFs) obtained from lanthanide metals, 3-Hydroxinaftalene-2,7-disulfonic acid (3-OHNDS) and two different phenanthroline derivates as ancillary ligands. The first is a family of 2Dcompounds with formula [Ln(3-OHNDS)(H2O)2], where Ln = La(1), Pr(2), Nd(3) and Sm(4). The addition of 1,10-phenanthroline (phen) in the reaction produces 1D compounds with general formula [Ln(3-OHNDS)(phen)(H2O)]·3H2O,where Ln= La(5), Pr(6), Nd(7) and Sm(8). Finally, the synthesis with 3,4,7,8-tetramethyl-1,10-phenanthroline (3,4,7,8-TMPhen) as an ancillary ligand results in the formation of the 3D [La(3-OHNDS)(3,4,7,8-TMphen)(H2O)] (9) compound.The photoluminescence (PL) properties of 1D and 2D compounds were fully investigated in comparison with the 3-OHNDSligand. One of the most important results was the obtentionof a white-light single-emitter without adding dopant atomsin the structure. With all these results in mind was possible establish structure-properties relationships.
