5-bis(diphenylphosphorylethynyl)thiophene: dpet, 2,7-bis(diphenylphosphorylethynyl)naphthalene: dpen, 1,3-bis(diphenylphosphorylethynyl)benzene: m-dpeb) ligands with thienyl, naphthyl, phenyl cores, and ethynyl groups. The glass-transition points were clearly identified for all Ln(III) coordination compounds (Tg = 65–87 °C). The Tb(III)/Eu(III) mixed coordination glass [Tb,Eu(hfa)3(m-dpeb)]3 (hfa:
报道了镧系元素 (Ln(III)) 配位化合物的玻璃化转变特性和温度敏感发光。通过掺入弯角氧化膦(2,5-双(二苯基磷酰乙炔基)噻吩:dpet,2,7-双(二苯基磷酰乙炔基)萘:dpen,1,3-双(二苯基磷酰乙炔基)苯:m)系统地提供玻璃成型性-dpeb) 配体与噻吩基、萘基、苯基核和乙炔基。所有 Ln(III) 配位化合物(Tg = 65–87 °C)的玻璃化转变点都被清楚地识别出来。Tb(III)/Eu(III) 混合配位玻璃 [Tb,Eu(hfa)3(m-dpeb)]3(hfa:六氟乙酰丙酮化物)也根据温度显示出绿色、黄色、橙色和红色光致发光。
