Crystalline Rubrene

Crystalline Rubrene

Why in news?

Recently, the researchers at the Institute of Advanced Study in Science and Technology (IASST) have found a new process for synthesizing crystalline Rubrene.


  • Crystalline Rubrene is a polycyclic aromatic hydrocarbon-based thin film which can be useful for the development of optoelectronic devices and also for preparation of Electronic Skin (E-Skin).
  • The new synthesis is a water-free, solvent-free, environmentally friendly one-step plasma process.
  • The resultant crystalline rubrene based film demonstrated optoelectronic properties and an Indian patent has been filed for the process.
  • Devices made of pyro-electric materials (that generate electric charge when they are heated or cooled) and piezo-electric materials (that generate electric charge under the effect of mechanical pressure), can help detect change in temperature and pressure.
  • Pyro-electric materials also show pyro-phototronic effect where pyro-electricity is associated with the change in temperature of a material when it absorbs photons.
  • Pyro-electric infrared detectors are well known for application in infrared sensing for space research, defense, remote sensing, and household appliances.
  • It may be useful as a tool for laboratory simulation of different biological systems for probing the organization and dynamics of those systems.
