A Catenane is a molecule consisting of two or more interlocked macrocyclic components. The name is derived from the Latin catena meaning "chain". They are conceptually related to other mechanically-interlocked molecules, such as rotaxanes, molecular knots or borromean ring. The synthesis of such entangled architectures has been made efficient through the combination of supramolecular chemistry with traditional covalent synthesis, however mechanically-interlocked molecules have properties that differ from both “supramolecular assemblies” and “covalently-bonded molecules”. ...more on Wikipedia about "Catenane"
Broadly, melanin is any of the polyacetylene, polyaniline, and polypyrrole "blacks" or their mixed copolymers. The most common form of biological melanin is a polymer of either or both of two monomer molecules: indolequinone, and dihydroxyindole carboxylic acid. In contrast, some fungal melanin is polyacetylene black. Melanin exists in the plant, animal and protista kingdoms, where it serves as a pigment. The presence of melanin in the archaea and bacteria kingdoms is an issue of ongoing scholarly disagreement. ...more on Wikipedia about "Melanin"
An organic semiconductor is an organic compound that exhibits similar properties to inorganic semiconductors, specifically the presence of a hole and electron conduction layer and a band gap. As with inorganic amorphous semiconductors, tunneling, localized states, mobility gaps, and phonon-assisted hopping also contribute to conduction. Like inorganic semiconductors, organic semiconductors can be doped. Highly doped organic semiconductors, for example Polyaniline (Ormecon) and PEDOT:PSS, are also known as organic metals. ...more on Wikipedia about "Organic semiconductor"

Perylene or perilene is a polycyclic aromatic hydrocarbon with chemical formula 20 12 and CAS number 198-55-0, occurring as a brown solid. It or its derivatives may be carcinogenic, and it is considered to be a hazardous pollutant. In cell membrane cytochemistry, perylene is used as a fluorescent lipid probe. ...more on Wikipedia about "Perylene"
Poly(3,4-ethylenedioxythiophene) or PEDOT (or sometimes PEDT) is a conducting polymer based on 3,4-ethylenedioxylthiophene or EDOT monomer. Advantages of this polymer are optical transparency in its conducting state, high stability and moderate band gap and low redox potential. A large disadvantage is poor solubility which is partly circumvented in the PEDOT:PSS composite. ...more on Wikipedia about "Poly(3,4-ethylenedioxythiophene)"
Poly(p-phenylene sulfide) (PPS) is the precursor to a conducting polymer of the semi-flexible rod polymer family. One of the usual reactants in production of PPS is p-dichlorobenzene. The PPS may be converted to the semiconducting form by oxidation or use of dopants. ...more on Wikipedia about "Poly(p-phenylene sulfide)"
Poly(p-phenylene vinylene) (PPV, or polyphenylene vinylene) is a conducting polymer of the rigid-rod polymer host family. ...more on Wikipedia about "Poly(p-phenylene vinylene)"
Polyacetylene (PA) is an organic polymer that can be converted to a conducting polymer of the rigid-rod polymer host family. As prepared by a Ziegler-Natta catalyst, with high levels of catalyst, the polymer is a silver, non-conductive film. Oxidation with iodine provides a 108 increase in conductivity. The 2000 Nobel Prize in Chemistry was awarded to Alan J. Heeger, Alan G MacDiarmid, and Hideki Shirakawa for this work. ...more on Wikipedia about "Polyacetylene"
Polyaniline (PANI) is a conducting polymer of the semi-flexible rod polymer family. Oxidation and/or doping during its synthesis provides the semiconducting properties. ...more on Wikipedia about "Polyaniline"
A Polypyrrole (PPy) is a chemical compound formed from a number of connected pyrrole ring structures. For example a tetrapyrrole is a compound with four pyrrole rings connected. Polypyrroles are conducting polymers of the rigid-rod polymer host family. ...more on Wikipedia about "Polypyrrole"
A rotaxane is a mechanically-interlocked molecule consisting of a dumbbell-shaped molecule that is threaded through a macrocycle or ring-like molecule. The two components are kinetically trapped as the two end-groups of the dumbbell (often called stoppers) are larger than the internal diameter of the ring, and thus prevent dissociation (unthreading) since this would require significant distortion of the covalent bonds. The name is derived from the Latin for wheel (rota) and axle (axis). ...more on Wikipedia about "Rotaxane"
