Special Issue Information

Dear Colleagues,

As a promising and efficient nanofabication method, self-assembly should eventually contribute to the development and manufacturing of materials and devices for real-world applications. The field of self-assembly is moving far beyond the early reports on fabrication, with a new focus on forming materials with programmable functions. Self-assembly is the spontaneous formation, from atoms, small molecules, or various types of building blocks, of highly organised functional nanoarchitectures on surfaces.

Organic nanomaterials having sophisticated structures, with desirable electronic, photonic, energy storage, and chemical formation functionalities, are expected to be engineered through self-assembly.

In this respect, specific self-assembly is particularly useful for making materials with selective structural features with nanometer precision. These systems can be established by non-covalent interactions, such as hydrogen or halogen bondings, van der Waals interaction, stacking, and electrostatic or organic–ionic material interactions. The design and the nature of the building blocks are key parameters not only to govern the formation of the self-assembled nanoarchitectures but also for programming their intrinsic functional properties.

This Special Issue welcomes the submission of original research papers or comprehensive reviews reporting the self-assembly of novel nanostructures or materials with programmable functionality. Papers related to significant advances in self-assembly not only in material fabrication but also as regards the functionalities, with potential applications to sensors or electronic devices, ect., are also encouraged.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
The ability to engineer sophisticated two-dimensional tessellation organic nanoarchitectures based on triangular molecules and on-surface-synthesized covalent multimers is investigated using scanning tunneling microscopy. 1,3,5-Tris(3,5-dibromophenyl)benzene molecules are deposited on high-temperature Au(111) surfaces to trigger Ullmann coupling. The self-assembly into a semi-regular rhombitrihexagonal tiling superstructure [...] Read more.
The ability to engineer sophisticated two-dimensional tessellation organic nanoarchitectures based on triangular molecules and on-surface-synthesized covalent multimers is investigated using scanning tunneling microscopy. 1,3,5-Tris(3,5-dibromophenyl)benzene molecules are deposited on high-temperature Au(111) surfaces to trigger Ullmann coupling. The self-assembly into a semi-regular rhombitrihexagonal tiling superstructure not only depends on the synthesis of the required covalent building blocks but also depends on their ratio. The organic tessellation nanoarchitecture is achieved when the molecules are deposited on a Au(111) surface at 145 °C. This halogen-bonded structure is composed of triangular domains of intact molecules separated by rectangular rows of covalent dimers. The nearly hexagonal vertices are composed of covalent multimers. The experimental observations reveal that the perfect semi-regular rhombitrihexagonal tiling cannot be engineered because it requires, in addition to the dimers and intact molecules, the synthesis of covalent hexagons. This building block is only observed above 165 °C and does not coexist with the other required organic buildings blocks. Full article
