Surface-confined supramolecular self-assembly has been the focus of extensive research in the past decade.1 A plethora of strategies have been developed and reported for surface patterning leading to novel applications in molecular electronics, photonics and nano-mechanical devices.2, 3 Nonetheless, despite of these numerous examples we are still at the early stages of fully exploiting them in viable, practical technologies since the main difficulty encountered upon applying nanomaterials in functional devices is that the functionalities and properties intrinsic to these materials are greatly limited by their inability to form ordered, integrated systems.4
In view of this, we propose a new molecular design approach based on the concept of ‘Nanoarchitectonics’ to demonstrate the growth of a nanoscale-range, well-ordered, fluorescent monolayer on graphene via the use of a ‘smart’ molecular building block. The design approach taken towards this ‘smart’ tecton is discussed, together with the studies of the resulting graphene-confined assemblies by scanning tunnelling microscopy (STM), and the optical properties of these fluorescent nano-surfaces by absorption and fluorescence spectroscopy.
nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
