The present invention describes an oligomer for use as a UV stabiliser. In particular, the oligomer is suitable for use as a UV stabiliser in a polymer matrix. The present invention also describes a method of forming said oligomer. The method of forming said oligomer comprises a polymerising step, wherein the polymerising step comprises forming a C—C bond on the hydroxyphenyl ring of a monomer. In preferred embodiments, the oligomer is formed from polymerizing bio-derived monomer such as curcumin, its hydrogenated analogue, and an aldol condensation product of cyclic ketone and vanillin.

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.
