Stirring the porphyrin alphabet soup functionalization reactions for porphyrins
(2011)Advances in the synthesis of unsymmetrically meso substituted porphyrins are based on the development of new total syntheses and porphyrin functionalization methods. These methods have replaced earlier mixed condensation ... -
Structural effects of meso-halogenation on porphyrins
(2021)The use of halogens in the crystal engineering of supramolecular porphyrin assemblies has been a topic of strong interest over the past decades. With this in mind we have characterized a series of direct meso-halogenated ... -
Synthesis and Crystal Structure of a Meso Meso Directly Linked Bisporphyrin
(2011)We report the synthesis and characterization of a meso-meso directly linked bisporphyrin 6 bearing both alkyl and aryl residues. Oxidative fusing results in a mesomeso, ???,???-linked bisporphyrin. The first crystal ... -
Synthesis and ligand binding properties of triptycene-linked porphyrin arrays
(2011)Multiporphyrin arrays are a complex class of molecules with numerous potential applications in energy transfer, photomedicine and light harvesting. We have developed a facile/versatile route to a class of triptycene ... -
Synthesis of Unsymmetrical meso-Substituted Porphyrins, 2. Porphyrin Dimers and Arrays
(2011)Current applications of porphyrins in medicine and optics, such as photodynamic therapy or nonlinear absorbers, increasingly require the use of far-red absorbing dyes. Modifications of the porphyrin structure to accommodate ... -
Synthesis of Unsymmetrically meso-Substituted Porphyrins
(2011)The continued development of new medicinal and industrial uses of highly substituted porphyrins, especially in the fields of photodynamic therapy, nonlinear optics and electron transfer systems, has led to a resurgent ... -
Tailoring Porphyrin (Nano)structures.
(2014)Porphyrins present one of the most ubiquitous classes of compounds in chemistry, optics, medicine, and materials science. This is a result of their multifaceted roles in nature and the wide range of tunable molecular ... -
Towards triptycene functionalization and triptycene-linked porphyrin arrays
(2020)Herein, 9,10-diethynyltriptycene is investigated for its use as a rigid isolating unit in the synthesis of multichromophoric arrays. Sonogashira cross-coupling conditions are utilized to attach various porphyrins and boron ... -
Weak Interactions and Conformational Changes in Core-Protonated A 2- and A x-Type Porphyrin Dications
(2020)Individual chemical motifs are known to introduce structural distortions to the porphyrin macrocycle, be it in the core or at the periphery of the macrocycle. The interplay when introducing two or more of these known ...
