The glass-transition properties and temperature-sensitive luminescence of lanthanide (Ln(III)) coordination compounds are reported. The glass formability was systematically provided by incorporation of bent-angled phosphine oxide (2,5-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 (T-g = 65-87 degrees C). The Tb(III)/Eu(III) mixed coordination glass [Tb,Eu(hfa)(3)(m-dpeb)](3) (hfa: hexafluoroacetylacetonate) also showed green, yellow, orange, and red photoluminescence depending on temperature.
