Amorphous Formability and Temperature-Sensitive Luminescence of Lanthanide Coordination Glasses Linked by Thienyl, Naphthyl, and Phenyl Bridges with Ethynyl Groups


Yuichi Hirai, Pedro Paulo Ferreira da Rosa, Takayuki Nakanishi, Yuichi Kitagawa, Koji Fushimi and Yasuchika Hasegawa
DOI: 10.1246/bcsj.20160379

Abstract

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 (Tg = 65–87 °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.

Thermosensitive Seven‐Coordinate TbIII Complexes with LLCT Transitions


Pedro Paulo Ferreira da Rosa, Takayuki Nakanishi, Yuichi Kitagawa, Tomohiro Seki, Hajime Ito, Koji Fushimi and Yasuchika Hasegawa
DOI: 10.1002/ejic.201800281

Abstract
Seven‐coordinate TbIII complexes with strong luminescence and thermosensing properties are reported. Mononuclear [Tb(tmh)3(PEB)] [tmh: 2,2,6,6‐tetramethyl‐3,5‐heptanedione, PEB: (diphenylphosphoryl)ethynyl]benzene and dinuclear [Tb2(tmh)6(m‐BPEB)] [m‐BPEB: 1,3‐bis(diphenylphosphoryl)ethynyl]benzene were characterized by single‐crystal X‐ray analysis. The quantum yields of [Tb(tmh)3(PEB)] and [Tb2(tmh)6(m‐BPEB)] were estimated to be 71 and 39 %, respectively. Thermosensing properties are evaluated by temperature‐dependent emission lifetime measurements (Arrhenius analysis), which are affected by the presence of ligand‐to‐ligand charge transfer (LLCT) bands. The LLCT bands are confirmed by DFT calculations.

Structural Manipulation of Triboluminescent Lanthanide Coordination Polymers by Side-Group Alteration


Yuichi Hirai, Pedro Paulo Ferreira da Rosa, Takayuki Nakanishi, Yuichi Kitagawa, Koji Fushimi, Tomohiro Seki, Hajime Ito and Yasuchika Hasegawa
DOI: 10.1021/acs.inorgchem.8b02367

Abstract
Novel Eu(III) coordination polymers with furan-based bridging ligands [Eu(hfa)3(Cy)]n and [Eu(hfa)3(Tol)]n (hfa: hexafluoroacetylacetonato, Cy: 2,5-bis(dicyclohexylphosphoryl)furan), Tol: 2,5-bis(di-p-tolylphosphoryl)furan) are reported. The rigidity of assembly steric structures was controlled by intermolecular interactions through the side groups in bridging ligands. They exhibited one of the best performances (thermal stability above 320 °C and external photoluminescence quantum yields of up to 71%) among reported lanthanide(III) compounds. The triboluminescence activity was demonstrated to be dependent on the mechanical stability of the coordination polymers, which was proportional to the number of hydrogen atoms in the side groups. The second example of a large TL/PL spectral difference in [Tb,Eu(hfa)3(Tol)]n also revealed discrete photophysical processes under the conditions of grinding and UV irradiation.
