Description

[12]Cycloparaphenylene CAS NO 1092522-75-2 is a highly specialized, macrocyclic hydrocarbon belonging to the cycloparaphenylene (CPP) family, characterized by its unique hoop-shaped structure composed of twelve para-linked benzene rings. This precise nanoscale architecture makes it a critical building block and model system in advanced materials science and supramolecular chemistry. It is essential for researchers and developers in nanotechnology, organic electronics, and molecular sensing who require structurally defined carbon nanostructures.

Application

• Carbon Nanotube Precursor & Synthesis: Serves as a precise, bottom-up template or "seeding" molecule for the controlled synthesis of uniform single-walled carbon nanotubes (SWCNTs) with specific chiralities.
• Supramolecular Chemistry & Host-Guest Systems: Acts as a rigid, π-conjugated macrocyclic host for encapsulating fullerenes (e.g., C60, C70), metals, or other molecules, enabling the study of novel complexes and energy/electron transfer processes.
• Organic Electronics & Photovoltaics: Investigated as a novel component in organic light-emitting diodes (OLEDs), field-effect transistors (OFETs), and light-harvesting systems due to its exceptional optoelectronic properties and defined exciton dynamics.
• Molecular Sensing & Nanoreactors: Utilized in the design of highly selective chemical sensors and as constrained environments (nanoreactors) to control and catalyze specific chemical reactions.
• Fundamental Research & Nanomaterial Modeling: Provides an ideal model compound for studying the properties of curved graphene segments, strain effects in aromatic systems, and the evolution of electronic structure in carbon-based nanomaterials.
