Abstract

Triboluminescence (TL), which is the light emission induced by mechanical stimuli, has attracted significant interest owing to its potential for energy conversion applications. Here, the TL mechanisms of chiral lanthanide complexes (LnL ^val , Ln = Eu, Tb, Sm, Dy, and Gd) were elucidated by focusing on the role of lamellar cleavage of the crystal structure. The modified drop tower system (DTS) quantifies mechanical stimuli used to observe the TL spectra. Chiral EuL ^val and TbL ^val exhibit intense TL, in contrast to the absence of TL in their racemic counterparts. Structural analyses revealed lamella‐like molecular stacking in the chiral crystals with anisotropic molecular orientations and flexibility along the c ‐axis. TL was reversibly observed by recrystallization when the crystal size was sufficiently large. Comparison of the TL and photoluminescence (PL) spectra, showed that TL of chiral LnL ^val was enhanced through photo‐antenna effects by the impact of lamellar cleavage. The TL values of the chiral Dy and Sm complexes were also evaluated. Furthermore, the absence of chemical reaction of the two nitrate ions with neighboring molecules in the lamella was confirmed. This system suggests the importance of the lamellar arrangement and provides potential design strategies for mechano‐responsive materials for TL activation of Ln complexes.

　View Summary

The near infrared (NIR) optical window enables to observe biological tissue noninvasively through photoimaging using luminophores. Particularly, the light in the NIR II region of 1000–1400 nm between strong absorption bands of H₂O and tissue chromophores is advantageous for photoimaging and phototherapies of deep tissue. Pt complexes possessing the high emission ability and the luminescence tunability are expected to be luminophores for deep imaging and photosensitizers of photodynamic therapy. Herein, the NIR II emission from Pt complexes designed by the strategy of the extension of ligand π conjugation and the aggregation by the Pt–Pt interaction from recent works is reviewed.

Abstract

We present the photoreaction of newly prepared bis(6,6’‐dimethyl‐2,2’‐bipyridine)(oxalato)rhodium(III) ([Rh(N N)₂(ox)]⁺) in CD₃OD. Photoirradiation of this complex causes the dissociation of ox, followed by the formation of the unprecedented Rh(III) complex with Rh−H and Rh−C σ bonds, [Rh(N N)(C N)(H)(CD₃OD)]⁺ (C N=[6,6’‐dimethyl‐2,2’‐bipyridine]‐3‐yl‐κC³,κN^1’). This hydride formation and cyclometallation spontaneously proceed owing to the conflict between the steric hindrance arising from the methyl groups of N N and the driving force for the structural change due to [Rh(N N)₂]⁺ formation. Although [Rh(N N)(C N)(H)(CD₃OD)]⁺ is initially converted to [Rh(N N)₂]⁺ by photoirradiation, it is immediately regenerated by the rollover cyclometallation of the [Rh(N N)₂]⁺ complex. [Rh(N N)(C N)(H)(CD₃OD)]⁺ undergoes H/D exchange for the H atoms in the Rh−H bond and at the 3, 3’‐positions of the N N ligand during the photoirradiation. DFT calculations predict with reasonable certainty the spontaneous structural change of [Rh(N N)₂]⁺ to [Rh(N N)(C N)(H)(CD₃OD)]⁺ and the subsequent photodriven Rh−C bond rupture leading to the formation of [Rh(N N)₂]⁺ accompanied by H/D exchange reactions.

Abstract

We report an unprecedented result of self‐aggregation of [Pt(L¹)Cl] (HL¹=1,3‐di(5‐carboxy‐2‐pyridyl)benzene) triggered by CO₂ in basic aqueous solution. The color of basic aqueous solution containing [Pt(L¹)Cl] changes from yellow to blue‐green during the aggregation resulted from a reaction with CO₂ in air. Upon CO₂ gas bubbling, strong and broad absorption bands of aggregate assigned to the metal‐metal‐to‐ligand charge‐transfer transition appeared at 701 and 1152 nm. Recrystallization of [Pt(L¹)Cl] from Na₂CO₃ aqueous solution afforded polymorphic crystals of red and blue‐green forms. A single X‐ray crystallography revealed that the red form of crystal consists of a Pt−Pt stacked dimer bridged by CO₃²⁻ ion and one of the carboxy groups of L¹ is deprotonated. An elemental analysis provided evidence that the blue‐green crystal is constructed by linear array consisting of the [Pt(L²)(CO₃)]³⁻ (HL²=1,3‐di(5‐carboxylate‐2‐pyridyl)benzene) units. The formation process of blue‐green aggregate in aqueous solution was monitored through a transient absorption spectrum, and the absorption of aggregates involved in the spectral change were examined by a global analysis. A singular value decomposition and kinetic analysis provide that there are four species resulted from the self‐assembling reaction in the solution and the maximal degree of aggregation is at least 32‐mer.

Abstract

Fluid dynamics, resulting from the macroscopic mechanical rotation of either a rotary evaporator or a magnetic stirrer, has been shown to selectively induce one of two enantiomers (mirror‐image structures) in certain nanoscale supramolecules. As an alternative to giving a chiral twist to synthesized supramolecules or polymers, it is a challenge to reproducibly prepare chiral species by only using macroscopic mechanical rotations. Demonstrated here is a highly reproducible method for rotary‐evaporation‐induced enantioselective H‐aggregation of achiral phthalocyanines. Chiral induction mechanisms are proposed by using the chiroptical‐sign‐based absolute structures. These results will provide insight to the origin of the homochirality of life, and serves as a pioneering study in a novel scientific field in terms of admixing nanoscale molecular chemistry and macroscopic fluid dynamics.

In this study, we succeeded in in-situ observation of harmonic light scattering signals of porphyrin J-aggregates induced by mechanical rotation for the first time, and clarified the dynamic chiral structure and chiral induction/dissociation mechanism of porphyrin J-aggregates. In addition, we succeeded in synthesizing chiral aggregates of phthalocyanine under mechanical rotation with high reproducibility for the first time, and clarified the chiral induction mechanism of the chiral aggregates composed of the phthalocyanine complex. From these research results, we have obtained new insight for controlling chirality by external stimuli.
