This work illustrates the use of basic statistical mechanics for rationalizing the loading of linear multitridentate polymers with trivalent lanthanides, Ln(III), and identifies the specific ionic sizes of europium and yttrium as promising candidates for the further design of organized heterometallic f-f′ materials. Using [Ln(hfac)3] (hfac = hexafluoroacetylacetonate) as lanthanide carriers, the thermodynamically controlled formation of Wolf type-II lanthanidopolymers [{Ln(hfac) 3}m(L4)] is modeled with the help of two simple microscopic descriptors: (i) the intrinsic affinity of Ln(III) for the tridentate binding sites fN3Ln and (ii) the intermetallic interactions δE1-2Ln,Ln operating between two occupied adjacent sites. Selective complexation modulated by anticooperative interactions favors the fixation of Eu(III) in semiorganized lanthanidopolymers [{Eu(hfac)3} m(L4)] displaying exploitable light-downshifting.

Fifteen p-terphenyls containing alkoxylated backbones with and without cyano groups on the phenyl moieties have been designed and synthesized. The influences of the position and the number of cyano groups on the phenyl moieties as well as the skeleton to

A new luminescent conjugated polymer (CN-P3PV) containing cyano groups as electron transporting units was synthesized by a Suzuki coupling reaction. CN-P3PV was characterized by 1H NMR, FT-IR, GPC, DSC, and TGA. The synthesized polymer possessed high thermal stability (Td = 360 °C, Tg= 151 °C), high electron affinity, and good thin-film forming ability. Electrical characterization of a double-layer organic LED based on the structure of ITO/CuPc/CN-P3PV/Ca/Ag showed high electron transporting ability and good electroluminescence performance with the emission of bright orange light.
