The history of metalloporphyrins dates back more than 200 years ago. Metalloporphyrins are excellent catalysts, capable of forming supramolecular systems, participate in oxygen photosynthesis, transport, and used as contrast agents or superoxide dismutase mimetics. Today, metalloporphyrins represent complexes of conjugated π-electron system and metals from the entire periodic system. However, the effect of these compounds on living systems has not been fully understood, and researchers are exploring the properties of metalloporphyrins thereby extending their further application. This review provides an overview of the variety of metalloporphyrins that are currently used in different medicine fields and how metalloporphyrins became the subject of scientists’ interest. Currently, metalloporphyrins utilization has expanded significantly, which gave us an opprotunuty to summarize recent progress in metalloporphyrins derivatives and prospects of their application in the treatment and diagnosis of different diseases.

“…Nano-building blocks are molecules with specific structures and shapes in nanometer sizes. They can be classified , as one-dimensional (1D) rod-like molecules (such as biphenyl and azobenzene), two-dimensional (2D) disk-like molecules (such as triphenylene − and porphyrin − ), and three-dimensional (3D) molecules [such as polyhedral oligomeric silsesquioxane (POSS) and fullerene (C60) − ] according to their shapes. Unlike BCPs, nano-building blocks often form ordered structures on the sub-10 nm length scale.…”

Hierarchically Ordered Structures of Rod–Rod Block Copolymers Containing Two Mesogen-Jacketed Liquid Crystalline Polymers

et al. 2019

In order to investigate the factors affecting the hierarchically ordered structures of the rod−rod block copolymers, SmPn based on two polynorbornene-based mesogen-jacketed liquid crystalline (LC) polymers PNb12POSS [having side-chain polyhedral oligomeric silsesquioxane (POSS) units] and PNb10PP (with a sidechain calamitic mesogen) was designed and synthesized by ring-opening metathesis polymerization, in which S and P refer to the two segments PNb12POSS and PNb10PP, respectively, whereas m and n refer to the ratios of monomer to catalyst during polymerization of PNb12POSS and PNb10PP, respectively. Investigation on the phase structures and behaviors of SmPn samples indicates that the LC and crystalline structures of the two segments are similar to their homopolymers. The PNb10PP segment forms a smectic A (SmA) phase with the ordered packing of the rod-like mesogens, and the PNb12POSS segment forms a hexagonal columnar (Col h ) phase with the crystal of POSS units. The volume fraction of PNb12POSS (f PNb12POSS ) plays an important role on the microphase separation of SmPn. The asymmetry between the two blocks becomes more pronounced with increasing f PNb12POSS , resulting in a larger bending curvature, and the microphaseseparated structure changes from lamellar (LAM) to hexagonally packed cylinders (HEX) for S10P30, S20P30, and S30P30. Moreover, the PNb12POSS segments in S20P30 and S30P30 form Col h phases that can be clearly observed by transmission electron microscopy. However, because of the slow kinetics of the polymer chains owing to the high molecular weight and rigidity, sample S30P120 having the lowest f PNb12POSS value cannot form ordered structures, while S80P120 only forms a HEX structure lacking regularity with a size of ∼40 nm.

Two star‐shaped mesogens with a (meso‐tetraphenylporphinato) zinc (II) core and bithiophene conjugated arms with 3,4,5‐trisdodecyloxyphenyl periphery were synthesized. One of these molecules was decorated with four fullerenes via an aliphatic spacer. This is the sterically overcrowded compound with an octapodal morphology. The other star lacks the fullerenes and provides free space between the conjugated arms. This mesogen does not aggregate in solution, but in solid state it forms a hexagonal columnar and a highly ordered oblique helical columnar phase, while the octopus molecule assemble in an amorphous solid. Photophysical studies of the octapodal compound in solution and the solid thin film reveal the formation of J‐type aggregates, in which the interaction between donors (porphyrin) and acceptors (fullerene) dominates leading to absorption bands in the NIR region of the spectra. The mixture of both compounds results in a self‐assembly which is called the Click procedure. Fullerenes of the octopus nanosegregate in the pockets of the star mesogens generating hexagonal columnar structures with a regular stacking along the columnar axis. Thus providing free space is a tool to control the competition between supramolecular interactions and nanosegregation. Such liquid‐crystalline donor‐acceptor structures may play a role in future LC photovoltaic applications.
