Novel EuIII coordination polymers [Eu(hfa)3(dpt)]n (dpt: 2,5‐bis(diphenylphosphoryl)thiophene) and [Eu(hfa)3(dpedot)]n (dpedot: 2,5‐bis(diphenylphosphoryl)ethylenedioxythiophene) with hydrogen‐bonded zipper structures are reported. The coordination polymers are composed of EuIII ions, hexafluoroacetylacetonato ligands, and thiophene‐based phosphine oxide bridges. The zig‐zag orientation of single...
Ein Chamäleon‐Luminophor: Ein Wärmefühler mit einer hohen Wärmestabilität wurde hergestellt (siehe Bild). Das Material besteht aus farbverändernden lumineszierenden Koordinationspolymeren, die EuIII‐ und TbIII‐Ionen enthalten. Das Koordinationspolymer zeigt bei Raumtemperatur eine Emissionsquantenausbeute Φ von 40 % und dient im Bereich von 200–500 K als Wärmefühler.
