“…Figure 4 shows the UV–vis spectra of monomer and polymers. All exhibited three characteristics absorption peaks from ferrocene at around ∼320,∼345 and ∼445 nm, which attributed to the ring MO–MO* transition and the d–d* transition, respectively, 47–48 whereas the ring MO–MO* transition is considerably affected by the spacer linker groups on the ferrocene rings 31,47 . Furthermore, the absorption intensity of peak at ∼445 nm is corresponding to the ferrocene moiety concentration in solutions.…”

Electrospun nanofibers from copolymers composed of ferrocene side chains and PEO100‐PPO65‐PEO100 (F127) were fabricated in chloroform and N,N–dimethyl formamide solutions (V/V = 95:5) at room temperature. Ferrocene‐containing multiblock copolymers (PFcMAn‐F127‐PFcMAn) were synthesized through reversible addition‐fragmentation chain transfer polymerization using s‐1‐dodecyl‐s''‐ (α, α'‐dimethyl‐α''‐acetic acid) trithiocarbonate (DDMAT) modified F127 with 2‐ (methacryloyloxy) ethyl ferrocencarboxylate (FcMA). The structures of as‐obtained chemicals were characterized by FTIR, 1H NMR, and 13C NMR. Additionally, the block copolymers molecular weight and polydispersity were measured using gel permeation chromatography. The electrochemical responsiveness of the polymers was investigated using cyclic voltammetry as well as the thermal stabilities of polymers and precursors were tested through DSC and TGA. The morphologies of electrospun fibers were observed through field emission scanning electronic spectroscopy and a fibrous diameter of 300–1100 nm was obtained. The results indicated that the suitable molecular weight of ferrocene ‐containing polymer would be processed in nanofibrous.

Individually, ferrocene and photochromic materials have several important attributes and applications. Ferrocene is a promising candidate of stimuliresponsive materials due to its electronic, electrochemical and magnetic properties. On the same lines, photo-sensitive materials are also an important class of stimuli-responsive materials which can be modified according to the needs.Recently, a lot of keen attention has been given to the combination of ferrocene with different photo-sensitive moieties to get novel functional materials. This review illustrates the research advances in the combination of ferrocene-based small molecules, self-assembled monolayers and polymers with photo-responsive compounds and their potential applications.

“…Ferrocene (Fc)‐containing polymers have attracted increasingly attention in the recent years due to their potential applications in molecular batteries, emissive and photovoltaic materials, catalysis, sensors, nanopatterning, smart hydrogels, and stimuli‐responsive materials . Recently, the emerging focus is the design, fabrication, and various applications of redox‐responsive polymeric carriers formed by using Fc‐containing polymers, which is primarily inspired by the redox chemistry of Fc …”

“…During the redox process of Fc, its sandwich structure is not destroyed, and only a slight change is observed in the length of the FeC bonds, accompanied by a reversible transformation between hydrophobicity and hydrophilicity . This is a great advantage for the construction of redox‐responsive polymer carriers . For example, Vancso and coworkers synthesized main‐chain Fc‐containing poly(ferrocenylsilane)s (PFSs) used to construct the redox stimulus responsive nanotubes and polyelectrolyte films by layer‐by‐layer (LbL) assembly method, which can be applied as controlled, redox‐triggered delivery systems to encapsulate and release guest molecules .…”

Novel well‐defined redox‐responsive Ferrocene (Fc)‐containing amphiphilic dendronized diblock copolymers are synthesized by the ring‐opening metathesis polymerization technique using Grubbs’ third‐generation olefin metathesis catalyst as the initiator. These dendronized block copolymers can self‐assemble into spherical micelles in aqueous solution. The size of self‐assembled micelles can be modulated by the composition (namely, the ratio of hydrophobic and hydrophilic segments) and concentration of the dendronized copolymers. The obtained micelles show reversible redox‐controlled self‐assembly behaviors using FeCl3 as oxidant and glutathione as reductant. Furthermore, the model molecule Rhodamine B is successfully loaded in these micelles, and the oxidation‐triggered controllable release is achieved by changing the type of oxidants (FeCl3 and H2O2) and their concentrations. This is the first example of redox‐responsive micelles self‐assembled by novel amphiphilic dendronized Fc‐containing block copolymers, and the present micelles are visualized to be potential candidates in many fields, especially in stimuli‐responsive drug delivery systems.
