The self-assembly behavior of porphyrin derivatives bearing different substituents is investigated on metal surfaces by Scanning Tunneling Microscopy (STM). Different methods to control the self-assembly process by skillful changes of the molecular substituents are developed. It is shown how one-dimensional wires as well as two-dimensional nanoporous networks can be formed by the same molecular compound depending on the surface coverage. The nanoporous networks can be altered in their pore characteristics and pore-to- pore distances in a controlled way. This is exploited to form a fully self-assembled supramolecular device. The characteristics of the device are studied in detail and it is shown that it can be operated by the tip of an STM. Finally, bimolecular systems are investigated. Here it is shown how the need to balance losses of entropy which is a common factor in all self-assembled networks, can be exploited to direct the self-assembly of such systems to form either separated phases or an intermixed network.

Π-conjugated systems of delocalized aromatic electrons along their backbones, including conjugated small molecules, oligomers, polymers, and carbonaceous materials, etc., have received considerable attention from a wide variety of scientific and technical communities. Compared to inorganic materials, the advantages of those based on π-tectons lie in their broad diversity, flexibility, and tunability with regard to structure/geometry/morphology, processability, composition, functionality, electronic/band structure, etc. In terms of sophisticated molecular engineering, these features endow them not only with excellent self-assembly properties but also with unique optical, electrical, mechanical, photophysical, photochemical, and biochemical attributes. This renders them promising scaffolds for advanced functional materials (AFMs) in numerous areas of general interest such as electronics, optics, optoelectronics, photovoltaics, magnetic and piezoelectric devices, sensors, catalysts, biomedicines, and others. With regard to the design/synthesis of novel π-tectons, the launch of diverse assembly/fabrication protocols, theoretical calculations, etc., the past several decades have witnessed tremendous advancements along this direction. Thus far, a vast array of high-performance π-tectons-based AFMs have been initiated. To some extent, the cooperative principle of π-πstacking and other noncovalent interactions has been revealed, and the structure-property relationships have been disclosed. Despite the existing progress, this field still faces challenges, for example: (i) the need for scalable assembly/manufacture under ambient conditions—with low-cost, facile, environmentally-friendly protocols (ii) clearer correlations bridging the underlying intricate relationships of each successive step in assembly/manufacture (iii) corresponding theoretical calculations for guiding the rational design of π-tectons that elucidate the cooperative principle of π-π stacking and other noncovalent interactions, as well as the principle of structure-performance correlation (iv) stability and durability, among the most important concerns regarding their commercialization The advancements accumulated during the past decades have established a solid foundation for the further development of π-conjugated systems-based AFMs. We believe that with unrelenting efforts from both scientific and technical communities of various backgrounds, their practical applications will eventually be fulfilled. This Research Topic aims to address the above-mentioned challenges
