Special Issue Information

Dear Colleagues,

In Nature, many systems contain structurally organized porphyrinoids including various enzymes, dedicated to oxygen transport, oxidation processes etc., or the light harvesting antennae and the reaction center involved in the photosynthetic processes. This observation opens the route to new challenges of synthesizing molecular architectures of growing size and structural complexity, for instance as potential models of the light harvesting complexes, but also as photonic and electronic wires. It rapidly appeared crucial to organize in space the chromophores in a way appropriate to induce the desired properties in the designed molecular architectures. For this purpose, both the structure of the molecules and their conformation need to be controlled. When interactions and recognition processes between one or more molecular architectures take place, all the rules of supramolecular chemistry are relevant to achieve the desired goal.

The present Special Issue, “Spatial Organization of Multi-Porphyrins for Pre-Defined Properties”, aims to collect and to disseminate some of the most significant and recent contributions in the very wide and highly interdisciplinary area. The scope is broad and includes covalently linked and self-assembled devices, as well as more sophisticated systems obtained when covalent linkage and supramolecular chemistry can work together. Furthermore, since chirality plays a pivotal role in the structural organization of vast majority of natural assemblies including photosynthesis owing to asymmetry of amino acids, the importance of chirality in some systems will also be covered in this issue.

Co-facial porphyrins have been designed to construct porphyrin tweezers with versatile molecular recognition capabilities. In this study, we synthesized metalloporphyrin–peptoid conjugates (MPPCs) displaying two metalloporphyrins on a peptoid scaffold with either achiral unfolded (1) or helical (2 and 3) secondary structures. Host–guest complexation of MPPCs was realized with various guests of different lengths and basicities, and the extent of complexation was measured by UV-vis and circular dichroism (CD) spectroscopic titration. Intermolecular and intramolecular chirality induction were observed on achiral and chiral peptoid backbones, respectively. Spectroscopic data indicated that a broad scope of achiral guests can be recognized by chiral 2; in particular, longer and more flexible guests were seen to bind more tightly on 2. In addition, chiral 2 provided a distinct CD couplet with dl-, d-, or l-Lys-OMe, which was a result of the diastereomeric host–guest complex formation. Our results indicated that MPPCs can recognize, contrast, and analyze various achiral, chiral, or racemic molecules. Based on co-facial metalloporphyrins present on peptoid scaffolds, we developed a novel class of porphyrin tweezers, which can be further utilized in asymmetric catalysis, molecular sensing, and drug delivery.
