Excellent supercapacitor and sensor performance of robust cobalt phosphinate ferrocenyl organic framework materials achieved by intrinsic redox and structure properties

Abstract

A new Co coordination polymer with phosphinates and Fc fragments was synthesized, which can be used as a water sensor and sorbent and also as a supercapacitor electrode.

Sterically Hindered Phosphonium Salts: Structure, Properties and Palladium Nanoparticle Stabilization

“…Organic salts have also shown their benefits in material science. Applications have been found for them as lubricants [ 17 ], in ionic liquid-based polymer electrolytes for Li-ion batteries [ 18 ] and supercapacitors [ 19 ] and in electrode functionalization [ 20 ].…”

Intrinsically conducting polymers and their combinations with redox-active molecules for rechargeable battery electrodes: an update

“…Ferrocene-containing coordination polymers have been suggested as electrode materials for lithium-ion batteries by Strekalova et al (2019) and Khrizanforov et al (2019). GO covalently modified with alkyne-terminated ferrocene by a click reaction subsequently mixed with Mn 3 O 4 and PANI was made into an electrode using additional carbon black and PVDF as a binder on a carbon paper support (Payami et al 2020) The author did not suggest use of the electrode as positive or negative one.…”

Electrochemical Applications of Ferrocene‐Based Coordination Polymers

“…The incorporation of redox-active Fc compounds into the modified electrodes can also facilitate recovery, stabilize the redox state, and enhance electron-mediator properties. [2] Khrizanforov et al designed a series of Fc phosphinate CPs with Cd, Zn, Ni, and Co ions [44,45,105,116,117] and selected the Cocontaining CP for SC performance evaluation. [116] This polymer features two-dimensional layers of 1,1'-ferrocenediyl-bis(Hphosphinate) and Co(II) ions, with water molecules acting as hydrogen bond donors located between two strands above the Co 2 + sphere ( Figure 10).…”
