Electrochromism light emitting diodes

These novel properties are the basis for a number of application including polymer light emitting diodes (LEDs), polymer light-emitting electrochemical cells (LECs), conducting polymers as electrochromic materials, polymer photodetectors and polymer photovoltaic cells. These application areas are discussed in detail in Section VII. 

An important area where technology and heterocyclic chemistry combine is that of electroactive organic materials. The applications of these materials, which extend beyond simple replacements for metals, include use as conductors, superconductors, semiconductors, batteries, transistors, sensors, light emitting diodes (LEDs), and related electrochromic applications. This area is of great commercial importance. 

Currently, most electrochromics have been used extensively in areas such as rechargeable batteries, sensors, membranes, light-emitting diodes, optical shutters, display panels, camouflage materials [94], earth-tone...
