Nanotechnology and new nanomaterials have an enormous impact on the modern science of technology The porphyrins are four pyrrole rings linked via methine bridges containing highly conjugated, planar and conjugated, rigid, and naturally occurring macrocyclic compounds, which play a very important role in the metabolism of living organisms. The porphyrin ring system is very stable and exhibits an aromatic character, in which the cavity space available for a coordinated metal has a maximum diameter of approximately 3.7 Å; this forms stable coordination complexes with metal ions, such as Zn, Cu, Fe, and Mg. Porphyrin derivatives play a key role in essential biological processes, such as photosynthesis, biological electron transport, oxygen transport, and metallo-enzymes.
On the other hand, the construction of nanosized supramolecular hosts via self-assembly of molecular components is a fascinating field of research. Such a fascinating class of architectures, in addition to their intrinsic intellectual stimuli, is of importance in many fields of chemistry and technology, such as material chemistry, catalysis, and sensor applications. The formation of supramolecules relays on non-covalent interactions (hydrogen bonding, hydrophobic/hydrophilic balance, π–π stacking interactions, van der Waals forces, inter/intramolecular forces or charge transfer) driven by the chemical information stored in the assembling molecules. Due to these interactions, the porphyrin derivatives tend to self-assemble into variable, well-defined structures: that is, into ordered geometrical patterns, such as rods, rings, wires, nanofibres, nanospheres, vesicles, squares, and micellar fibres. This allows, for example, the formation of a solid system with tailored features through large well-defined porphyrin aggregates in solution that can be spontaneously transferred onto a solid surface.
This Special Issue aims to provide a forum for the dissemination of the latest information on recent developments in the porphyrin chemistry, with which to develop of nano- and bio-technological tools in various fields, such as sensing, photochemistry, catalysis, biology, and solar cell applications.

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. Nanomaterials is an international peer-reviewed open access monthly journal published by MDPI.
