Preparation of redox- and photo-responsive ferrocene- and azobenzene-based polymer films and their properties

Research advances in the synthesis and applications of ferrocene‐based electro and photo responsive materials

“…These gratings can have strong potential for holographic data storage and templating (Scheme ) . Redox and photo‐active polymer films were prepared by free radical copolymerization and their ability to store data was checked . Three different copolymers were synthesized in this respect.…”

“…Finally, ferricenium ions recovered to initial state by the chemical or electrochemical stimulus. This whole process was stable and reversible during the course of application …”

“…It is also reported that the ferrocene‐based system affects the isomerization behavior of photoresponsive moieties . Based on this phenomenon, much attention has been given to the ferrocene‐based photochromic systems to extend their existing applications such as information storage devices, molecular switches, photo‐mechanical systems, micro patterning and nonlinear optical media to get multifunctional systems . This attractive behavior led the focus towards the combination of electro and photochromic moieties.…”

Ferrocenyl amphiphilic Janus dendrimers as redox‐responsive micellar carriers

“…[35,36] For example, Liu et al described a redox-controlled drug delivery system based on ferrocene (Fc)-containing amphiphilic block copolymers (PEG-b-PMAEFc) that were fabricated via atom transfer radical polymerization (ATRP) using a PEGbased macro-ATRP agent. [37][38][39][40][41][42] And notably, this redox process is attributed to the gain and loss of one electron, and the molecular structure of Fc group is not destroyed, which is a great benefit for the reversible self-assembly and disassembly of Fc-containing amphiphilic macromolecules.
