Hot Article: Propylenedioxythiophene (ProDOT)–phenylene copolymers allow a yellow-to-transmissive electrochrome

Researchers from University of Florida have developed the first cathodically colouring yellow-to-transmissive switching electrochromic polymer.

Electrochromic displays require the modulation of three subtractive primary colours (red, yellow and blue or cyan, magenta and yellow) in order to express all of the colours in the spectrum. This work reports the first polymer that is yellow in its neutral state and highly transmissive in its oxidised state. The polymer achieves a 70% transmittance contrast at its absorption maximum and is capable of a full switch in under one second, therefore showing promise as a component of a full multicolour electrochromic device.
