Chlorographene

[3] Although graphene is one of the most mechanically strong material having a wide range of extraordinary properties, practical device applications are limited by its metallic behavior and sensitivity to surface adsorbates.

In particular, band gap engineering of graphene through chemical modification, such as oxygenation,[4] hydrogenation[5] and fluorination[6][7] is appealing for electronic applications, since the scalable fabrication of graphene-based devices without disturbing the strong honeycomb lattice has become possible.

Easy synthesis, high-quality insulating behavior and extraordinary mechanical strength of fluorographene (CF) have inspired intense research on other halogen decorated graphene derivatives.

Theoretical investigations have revealed that the covalently bonded chair conformation of chlorographene (formulated as CCl) is found to be stable even at room temperature.

[clarification needed] Its electronic properties are more sensitive to applied strain than other graphene derivatives such as graphane and fluorographene.
