“…8 Among known TL coordination compounds, complexes of rare earth elements, Eu III and Tb III , are the most widely known. [9][10][11] A limited number of triboluminescent transition metal (TM) complexes have also been reported, including Ru II , 12 Pt II , 13 Mn II , [14][15][16] and Cu I . [17][18][19][20][21][22] Considering that Cu is one of the most abundant and inexpensive metals, TL materials based on Cu present a practical alternative to currently utilized Eu-and Tb-based materials.…”

“…Nevertheless, the TL spectra are identical to their corresponding PL spectra, indicating that the symmetry of the complexes did not change upon fracture of the crystal structure. If so, the splitting of the hypertensive peaks would have been altered [19].…”

Triboluminescence of Centrosymmetric Lanthanide β-Diketonate Complexes with Aggregation-Induced Emission

Triboluminescence (TL) is a form of light emission induced upon mechanical forces on the material. However, our understanding of this phenomenon is still unclear and more examples are therefore needed in order to elucidate its mechanism. In this work, two types of TL complexes, [Eu(pp-dbm-Cl2)3phen] and [Eu(mm-dbm-Cl2)3phen], which also displays aggregation-induced emission (AIE) were synthesized and investigated for its photo-physical and crystal structural properties. These complexes were crystallized in a centro-symmetric space group P21/n, and remarkably, displayed TL upon grinding that may be due to the presence of extensive π···π, C-H···π and C-H···Cl-C interactions in the close molecular packing of its structure. This rare example deviates from the widely accepted mechanism of TL, hence widening the scope of our understanding in the area.

“…Triboluminescence of lanthanide coordination polymers was reported by Kitagawa, Hasegawa, and coworkers. 137 The used lanthanide coordination polymers are composed of Tb III and Eu III emission centers, hexafluoroacetylacetonate antenna, and 2,5bis(diphenylphosphoryl)-furan bridging ligands. Emission for triboluminescence (yellow) of Tb III /Eu III -mixed coordination polymer was apparently different from that for photoluminescence emission upon UV light irradiation (reddishorange).…”

Nanoarchitectonics is a concept envisioned to produce functional materials from nanoscale units through fusion of nanotechnology with other scientific disciplines. For component selection, coordination complexes with metallic elements have a wider variety of element selection because metallic elements cover ca. 80% of the periodic table of the elements. Application of nanoarchitectonics approaches to coordination chemistry leads to huge expansion of this concept to a much wider range of elements. Especially, coordination asymmetry strategy architects asymmetrical and/or chiral structures and/or electronic states through formation of metal coordination complexes, leading to functional material systems in certain anisotropy and selectivity. This review article presents expansion of the nanoarchitectonics concept to coordination asymmetry through collecting recent examples in the field of coordination asymmetry. Introduced examples are classified into several categories from various viewpoints: (i) basic molecular and material designs; (ii) specific features depending on interfacial media, space and contact with bio-functions; (iii) functions; (iv) supporting techniques such as analyses and theory.
