OMIEC, organic mixed ionic-electronic conductors for energy storage, electrochromic displays, bioelectronics, sensors, electrocatalysis, neuromorphic devices, thermoelectrics, and actuators

Mixed ionic-electronic conductors, also known as mixed conductors, are an increasingly important category of materials with applications in energy storage, electrochromic displays, bioelectronics, sensors, electrocatalysis, neuromorphic devices, thermoelectrics, and actuators.

Mixed conductors exhibit both ion and electron/hole conductivity, and ionic-electronic coupling (i.e., capacitance), allowing them to effectively transduce ionic signals to electronic ones, and vice versa.

In recent years, new mixed conductors have been developed beyond the traditional metals oxides and phosphates to include (semi)conducting polymers, radical polymers, perovskites, and hybrid organic-inorganic materials, enabling improved performance and new functionalities.

Structured below are examples of polymeric mixed conductors from 1-Material Inc.

n-PBFDO, PBFDO, n-PBDF, n-type polymer, counter partner PEDOT, for OECT, capacitors, transparent electrode

Would the emerging poly(benzodifurandione)[PBDF, PBFDO] reported having an unprecedented high electrical conductivity upon reduction (“n-doping”) with protons, high optical transparency and low work-function, be outmatching the predominant counter-partner PEDOT:PSS?  Please check links below to find more.

Indoor OPV IoT internet of thing ambient light, OPD, donor and acceptor

Highly tunable optical absorption, large absorption coefficients, and small leakage currents under dim lighting conditions make OPVs promising candidates for operating various small scale and low-power consumption indoor electronic devices. Theoretically, the maximum efficiency at Eg = 1.90–2.20 eV was calculated to be 50% under FL lamps and LEDs,  practically over 30% of efficiency has been achieved in the many labs.

Here listed below are examples of our indoor OPV materials selected for further validation and optimization, we are very much looking forward to your suggestions.
