A bottom up unique method build the holy graphene from molecular blocks. The molecular blocks used define the size and shape of the pores, which are identical with atomic precision. We can also control the chemical functionalization of the material.
This material has semiconducting properties with a bandgap similar to Si, opening new applications for graphene-based materials.
This new material can be used for sieving, sensing, (opto)electronics or its combinations.
Researchers have devised a flexible method for the bottom-up synthesis of nanoporous graphene. Grow to order from molecular building blocks, the result is a range of versatile 2D membranes with high-density periodic arrays of subnanometer pores fabricated with atomic precision and full control over its chemical functionalisation. It is a totally new material which adds tunable permeability and semiconductivity to graphene properties, opening it up to new multifunctional applications that require pores, a bandgap, or both.
Applications:
(opto)electronics:as field.effect transistor (FET) for flexible transparent electronics, and near infrared and visible optoelectronics based on gate- modulated plasmonics.
Membrane applications:the mechanical properties of the material point to its use as a highly selective molecular sieve. This selectivity can be enhanced through the design of the building blocks.
Multifunctional applications:emerge from the combination of mechanical and (opto)electrical properties, for example in gate-controlled sieveing and sensing (FET sensors) or in gate-controlled electrical DNA sequencing.
