Efficient non-halogenated solvent for the template-free solution synthesis of ultralong copper octaethylporphyrin nanowire networks with strong photoswitching properties

Abstract

A non-halogenated solvent was used for the one-step and scalable synthesis of extremely high aspect ratio organic semiconducting nanowires of CuOEP which exhibit excellent photoswitching effects with reliable reproducibility and superior stability.

Porphyrin Nanowire Bundles for Efficient Photoconductivity, Photoemission, and Generation of Singlet Oxygens toward Photodynamic Therapy

“…One-dimensional nanostructures with a high aspect ratio are primarily advantageous to maximize the interfacial area which is accessible by the chemical substances in the catalytic cycles or electron/energy-harvesting processes. Motivated by the strong intermolecular interaction of porphyrin/phthalocyanine cores assisted by the center metal interaction and/or those of peripherals, successful 1D assemblies were achieved under controlled cross-sectional geometry − and demonstrated as electronic conductive wires, − efficient surface catalysts, excitation energy-harvesting networks, − sensing platforms, optical switches, and prisms. , Most of all of the structures are thermodynamically favored predominantly by intermolecular dispersion forces and partially by the formation of hydrogen bonding. Stabilization of the nanoarchitectures has also been addressed by the dimensional growth of the assemblies.…”
