*Resumen de la charla: *

On-surface reactions, via programmed interactions of molecular building 
blocks, have recently emerged as a promising route to synthesise 
atomically precise materials from the ‘bottom-up’. This approach ensures 
exquisite atomic-scale control of the structural and chemical 
functionalization, allowing to design a vast number of carbon-based 
nanoarchitectures not available by traditional solution chemistry nor 
with the ‘top-down’ methodologies. In particular, graphene nanoribbons 
(GNRs) with different structures can be synthesized with atomic 
precision and fine-tuned electronic band gap.

In this talk, I will describe the recent advances in the on-surface 
synthesis field. Then, I will discuss our recent results to synthetize 
atomically precise nanoporous graphene, graphene nanoribbons and their 
chemical functionalization and how to organize them into superlattices.

At the end of the day, this talk will demonstrate the full path to 
synthetize a semiconducting graphene material with a bandgap similar to 
that of silicon, its atomic-scale characterization, and its 
implementation in an electronic device. Further potential applications 
include in highly selective molecular filtration and sensing systems*.*

*Resumen CV: *Dr. César Moreno received his Ph.D in Material Science at 
the Institute of Materials Science of Barcelona (ICMAB) in 2010 and he 
moved as postdoctoral researcher at the Nano-engineering research center 
at the Polytechnic University of Catalonia. In 2012, he moved to the 
National Institute of Materials Science (NIMS) in Tsukuba-Japan, were he 
was ultimately promoted as permanent researcher. In 2016 returned to 
Barcelona, where he presently works as a senior researcher at ICN2. His 
work focuses in the atomically precise manufacturing of low-dimensional 
organic materials with multiple applications. He was awarded the 
Molecule of the Year 2018  prize by the American Chemical Society, and 
also holds the distinguished Research Award by the Spanish National 
Research Council (CSIC).
