“…Complementary H-bonded melamine-barbituric acid motifs can form rosettes or tapes with porphyrins appended to the melamine45 or to the barbituric 111. More robust structures can be formed by introduction of a strapped porphyrin unit to the cyanuric acid moiety, and this can be used as supramolecular receptors for binding large molecules 103,111.…”

The self-assembly and self-organization of porphyrins and related macrocycles enables the bottomup fabrication of photonic materials for fundamental studies of the photophysics of these materials and for diverse applications. This rapidly developing field encompasses a broad range of disciplines including molecular design and synthesis, materials formation and characterization, and the design and evaluation of devices. Since the self-assembly of porphyrins by electrostatic interactions in the late 1980s to the present, there has been an ever increasing degree of sophistication in the design of porphyrins that self-assemble into discrete arrays or self-organize into polymeric systems. These strategies exploit ionic interactions, hydrogen bonding, coordination chemistry, and dispersion forces to form supramolecular systems with varying degrees of hierarchical order. This review concentrates on the methods to form supramolecular porphyrinic systems by intermolecular interactions other than coordination chemistry, the characterization and properties of these photonic materials, and the prospects for using these in devices. The review is heuristically organized by the predominant intermolecular interactions used and emphasizes how the organization affects properties and potential performance in devices.

“…In contrast, we have studied the end‐group effect on the macroscopic self‐assembly, which leads to formation of a biocompatible hydrogel. Although fruitful phenomena related to the end‐group effect on microscopic molecular conformation and nanoscale aggregates have been observed in various organic molecules in selective solvents,1–4 reports of the end‐group effect on the condensed‐state behavior of self‐assembled soft matter are rather limited.…”

En„d“scheidend: Alkyl‐Endgruppen können in einer solartigen Suspension einen thermoreversiblen Sol‐Gel‐Übergang auslösen, indem sie das makroskopische Selbstorganisationsverhalten beeinflussen. Das Bild zeigt PLGA‐PEG‐PLGA‐Triblockcopolymer/Wasser‐Mischungen in Sol‐ (Polymer a), Gel‐ (Polymere b und c) und Entmischungszuständen (Polymer d). PLGA=Poly(milchsäure‐co‐glycolsäure), PEG=Polyethylenglycol.

In the end: Alkyl end groups can induce a thermoreversible sol–gel transition in an otherwise sol‐like suspension by affecting the macroscopic self‐assembly behavior. The picture shows PLGA‐PEG‐PLGA triblock copolymer/water mixtures in the sol (polymer a), gel (polymers b and c), and precipitation states (polymer d). PLGA=poly(lactic acid‐co‐glycolic acid), PEG=poly(ethylene glycol).
