Novel 2-D Material Offers a Band Gap and Self Assembly

The competitive field of two-dimensional materials has added another rival to graphene to its ranks. A collaboration between MIT and Harvard University researchers has yielded what observers are heralding as a major advance in the synthetic design of novel semiconducting materials. The Boston-area researchers have developed a new 2-D material that not only has an inherent band gap—which graphene lacks—but self-assembles, promising easier avenues to mass production.

The material is a combination of nickel and an organic compound called 2,3,6,7,10,11-hexaiminotriphenylene (HITP). The resulting material belongs to a class of materials known as metal-organic frameworks (MOFs) that are compounds in which metal ions are coordinated to rigid organic molecules to form a porous material that can be one-, two-, or three-dimensional.
