Synthesis and structural, electrochemical and photophysical studies of triferrocenyl-substituted 1,3,5-triphenylbenzene: a cyan-light emitting molecule showing aggregation-induced enhanced emission

Abstract

Triferrocenyl-substituted 1,3,5-triphenylbenzene was successfully synthesized in high yield. Single-crystal X-ray diffraction experiments revealed that internal rotations of ferrocenyl moieties are significantly restricted in the solid phase and that there are...

A chromatography-free total synthesis of a ferrocene-containing dendrimer exhibiting the property of recognizing 9,10-diphenylanthracene

“…It should be also stressed that analytical studies were performed in aqueous environment with small addition of DCM (not higher than 3%). Finally, it is worth to note that no significant interaction between the parent subunit structure of Fc-den, i.e., 1 without formyl functionalities, which was recently reported by our group 30 , was observed during the electrochemical assays. It means that the organized, πconjugated structure of Fc-den is indeed essential for providing the studied electrochemical recognition ability.…”

“…The Fc units were attached do the 1,3,5-triphenylbenzene skeletons via imine bonds. It is known that by applying too high a potential >1.1 V such bonds can be broken relatively easily, as representatively shown in our previous report on Fcfunctionalized 1,3,5-triphenylbenzene 30 . However, in the case of this compound the decomposition of imine bond was not observed even the applied potential is higher than 1.3 V. Due to the presence of phenyl rings in the Fc-den structure, this compound can be an excellent receptor for other aromatic compounds.…”

Aromatic Dendrimers Bearing 2,4,6-Triphenyl-1,3,5-triazine Cores and Their Photocatalytic Performance

“…These changes were ascribed to the higher content of 1,3,5-triazine skeletons in D2 (four units) in comparison to D1 (one unit) and the expansion of a π-conjugation system. ,, Only slight changes between the emission spectra measured in other selected solvents were found (Figures S10–S11). Emission quantum yields (Φ F ) (λ ex = 315 nm) estimated by the relative method were 0.32 and 0.78, for D1 and D2 , respectively.…”
