Elucidating Atropisomerism in Nonplanar Porphyrins with Tunable Supramolecular Complexes
(2021)Atropisomerism is a fundamental feature of substituted biaryls resulting from rotation around the biaryl axis. Different stereoisomers are formed due to restricted rotation about the single bond, a situation often found ... -
Ethynylphenyl-Derivatized Free Base Porphyrins: Anodic Oxidation Processes and Covalent Grafting onto Glassy Carbon Electrodes
(2020)In six of seven cases, direct anodic oxidation of the ethynyl group of an ethynylphenyl-derivatized free-base porphyrin gave modified glassy carbon electrodes in which the porphyrin was strongly surface-bound, most likely ... -
Exploring the relationship between structure and activity in BODIPYs designed for antimicrobial phototherapy
(2020)A synthetic strategy to BODIPY dyes is presented giving access to a range of new compounds relevant in the context of antimicrobial photodynamic therapy (aPDT). BODIPYs with the 8-(4-fluoro-3-nitrophenyl) and the ... -
Exploring the reversible host–guest chemistry of a crystalline octanuclear Ag(i) metallosupramolecular macrocycle formed from a simple pyrazinylpyridine ligand

Functionalization of Deutero- and Protoporphyrin IX Dimethyl Esters via Palladium-Catalyzed Coupling Reactions
(2019)Herein, we report the functionalization of the β-positions of deutero- and protoporphyrin IX dimethyl ester. Initial halogenations were carried out on both deutero- and protoporphyrin IX dimethyl ester. While previously ... -
Glycosylated naphthalimides and naphthalimide Tröger's bases as fluorescent aggregation probes for Con A
(2019)Herein we report the synthesis of fluorescent, glycosylated 4-amino-1,8-naphthalimide (Nap) 1, and the related 1,8-naphthalimides Tröger's bases (TBNap) 2 and 3, from 1,8-naphthalic anhydride precursors, the α-mannosides ... -
Grain boundary-mediated nanopores in molybdenum disulfide grown by chemical vapor deposition
(Royal Society of Chemistry, 2017)Molybdenum disulfide (MoS2) is a particularly interesting member of the family of two-dimensional (2D) materials due to its semiconducting and tunable electronic properties. Currently, the most reliable method for obtaining ... -
Graphene Oxide Functionalized with Cationic Porphyrins as Materials for the Photodegradation of Rhodamine B
(2020)Two noncovalent nanohybrids between cationic porphyrin (free-base TMPyP and zinc(II) ZnTMPyP) bearing cationic (N-methylpyridyl) groups and graphene oxide (GO) were constructed with the aim of generating a photocatalyst ... -
A Heterometallic Porphyrin Dimer as a Potential Quantum Gate: Magneto-Structural Correlations and Spin Coherence Properties
(2023)In the development of two-qubit quantum gates, precise control over the intramolecular spin-spin interaction between molecular spin units plays a pivotal role. A weak but measurable exchange coupling is especially important ... -
