Abstract
This review links various areas of inorganic chemistry around the themes developed by our research group during the last four decades. It is firstly based on the electronic structure of iron sandwich complexes, showing how the metal electron count dictates their reactivities, with various applications (via C-H activation, C-C bond formation) as reducing and oxidizing agents, redox and electrocatalysts and precursors of dendrimers and catalyst templates through bursting reactions. Various electron-transfer processes and consequences are explored, including the influence of the redox state on the acidity of robust ligands and the possibility to iterate in situ C-H activation and C-C bond formation to build arene-cored dendrimers. Examples of how these dendrimers are functionalized are illustrated using the cross olefin metathesis reactions, with application to the synthesis of soft nanomaterials and biomaterials. Mixed and average valence complexes give rise to remarkable subsequent organometallic reactions, including the salt influence on these reactions. The stereo-electronic aspect of these mixed valencies is pointed out in star-shaped multi-ferrocenes with a frustration effect and other multi-organoiron systems, with the perspective of understanding electron-transfer processes among dendrimer redox sites involving electrostatic effects and application to redox sensing and polymer metallocene batteries. Dendritic redox sensing is summarized for biologically relevant anions such as ATP2- with supramolecular exoreceptor interactions at the dendrimer periphery in parallel with the seminal work on metallocene-derived endoreceptors by Beer's group. This aspect includes the design of the first metallodendrimers that have applications in both redox sensing and micellar catalysis with nanoparticles. These properties provide the opportunity to summarize the biomedical (mostly anticancer) applications of ferrocenes, dendrimers and dendritic ferrocenes in biomedicine (in particular the contribution from our group, but not only). Finally, the use of dendrimers as templates for catalysis is illustrated with numerous reactions including C-C bond formation, click reactions and H2 production reactions.

Abstract
External-stimuli-responsive smart viscoelastic systems have the potential for diverse applications. Worm-like micelles (WLMs) are distinct viscoelastic systems. Several stimuli-responsive WLMs have been reported thus far, in which modifications are triggered by pH variations, redox reactions, temperature shifts, and light. However, sugar-responsive WLMs have not been reported. Phenylboronic acid (PBA) reversibly forms cyclic ester with cis-diol compounds; therefore, it serves as a cis-diol sensor for compounds such as glucose (Glc) and fructose (Fru). Adding PBA to cetyltrimethylammonium bromide (CTAB) in a basic medium induces the transition of spherical micelles to WLMs. This is accompanied by a substantial increase in the viscosity of the CTAB/PBA system. Notably, the addition of Glc to the CTAB/PBA system induces the transformation of the WLMs into spherical micelles or short rod-like micelles. In this review, we describe diol-responsive micellar systems based on PBA and their rheological properties.

Abstract
We had previously confirmed a glucose-responsive decrease in the viscosity of cetyltrimethylammonium bromide (CTAB) and phenylboronic acid (PBA) wormlike micelle (WLM) systems. However, the mechanisms of the formation of WLMs and the decrease in viscosity with glucose addition have not been determined. In this study, we elucidated the mechanisms using 3-fluorophenylboronic acid (3FPBA) based on 11B NMR and 19F NMR analyses. The system in 60 mM CTAB/60 mM 3FPBA at pH 7.4 demonstrated high viscoelasticity, and the formation of WLMs in the system was confirmed by rheological characteristics. The 11B NMR spectrum at pH 7.4 revealed that 3FPBA existed in a neutral form with sp2-hybridized boron; however, the 11B signal disappeared in the presence of CTAB. In contrast, 19F NMR studies indicated that the quaternary ammonium ion of CTAB interacts with the phenyl group of 3FPBA in the sp2 form via cation-π interactions. PBA derivatives react with various polyols; thus, we investigated the change in the viscous system after the addition of sugar and sugar alcohols. The viscosity of the WLMs decreased with increased polyol concentration, especially those of fructose and mannitol, in which the decrease was apparent at 40-160 mM polyols. The 19F NMR spectra revealed that polyol addition induced decrease in the sp2 form of 3FPBA and increase in the sp3 form of 3FPBA. Based on the results, we propose the following mechanism of the polyol response: (1) The WLMs are stabilized by CTAB and 3FPBA in the sp2 form using cation-π interactions as the driving force. (2) When polyol is added to the system, the sp2 form of 3FPBA decreases and its sp3 form increases. (3) This change means that the structural component of WLMs decreases, which induces the disruption of WLMs, and the viscosity decreases. The formation and deformation mechanisms of the WLMs determined in this study are notable because 3FPBA interacts as a neutral compound, whereas CTAB often interacts with anionic aromatic compounds to form WLMs. Without 19F NMR measurements, these mechanisms would not have been discovered.

Abstract
HYPOTHESIS Hybrid surfactants containing both alkyl and fluoroalkyl chains within the same molecule where modification of the azobenzene group will enable us to switch the superhydrophobic nature with an external light source, and the optical behavior will vary depending on the structure of the hydrophobic chains. EXPERIMENTS Surface activity and its optically-induced variation of the azobenzene-modified hybrid surfactants were characterized using the surface tensiometry, UV-vis and NMR spectroscopy and theoretical calculation. FINDINGS The hybrid surfactants are superhydrophobic in nature reducing the surface tension of water to near 20 mN/m. Photo-isomerization of the azobenzene group induces a drastic surface tension variation (Δγ), and particularly the compositions containing the octyl-fluorocarbon chain exhibit remarkable Δγ as much as 30 mN/m which is even higher than that of the conventional surfactants (Δγ ≈ 14-20 mN/m). Theoretical calculation suggests significantly higher hydrophilicity of the cis isomer, causing the drastic switch in the surface activity. These results indicate the promise of the hybrid surfactants as efficient surface/interface manipulators.
