Described herein are associative polymers capable of controlling a physical and/or chemical property of non-polar compositions and related compositions, methods and systems. Associative polymers herein described have a non-polar backbone and functional groups presented at ends of the non-polar backbone, with a number of the functional groups presented at the ends of the non-polar backbone formed by associative functional groups capable of undergoing an associative interaction with another associative functional group with an association constant (k) such that the strength of each associative interaction is less than the strength of a covalent bond between atoms and in particular less than the strength of a covalent bond between backbone atoms.

The present invention provides an organic nano-grid, a nano-polymer thereof and a preparation method therefor. The organic nano-grid has a general formula (I), and the nano-polymer has a general formula (II), wherein R.sub.1 is an alkyl chain, R.sub.2 is halogen or an electroactive group, and X may comprise a heteroatom such as N, O and S, and n is a natural number from 1 to 10. A nano-connection strategy is applied to the construction of a one-dimensional nano-polymer. The polymer starts from a monomer A.sub.2B.sub.2 to form a corresponding nano-polymer by a Friedel-Crafts polymerization cyclization reaction.

Provided are a polymer containing S,S-dioxide-dibenzothiophene in backbone chain with content-adjustable triarylamine end groups, and a preparation method and an application thereof. Triarylamines hole-transport small molecules are introduced into the polymer end group, and a content of the triarylamine end groups can be adjusted by controlling a polymer molecular weight, so that the polymer has better electron-transport and hole-transport capabilities, and charge carrier transport can be balanced, so that more exciton recombination takes place effectively, thus improving the luminous efficiency and stability of the polymer. The polymer is prepared by a Suzuki polymerization reaction and does not require synthesis of new monomers. The polymer material is used for preparing highly effective and stable monolayer devices, and is dissolved directly in an organic solvent, then spin-coated, ink-jet printed, or printed to form a film.

Compositions for forming polymer layers useful in the manufacture of optical devices, particularly optical waveguides, and methods of forming such devices are provided.
