To provide a material which has a high carrier-moving degree and a high lowest excitation triplet energy level and can be coated in a laminated state, to provide a new light emission element which realizes a good carrier balance, has the characteristics of low voltage driving, high brightness and high light emission efficiency, and has good storage durability at high temperature, and to provide a material which permits the selective injection and transportation of holes or electrons in high mobility as an electronic device material and can simply be produced.

The topochemically polymerizable compound represented by the general formula (I) (Ak is an alkylene; Cy is an aromatic group having one or more heterogeneous atoms and having totally six or more atoms) [typical examples are compounds of formulas (II) and (III)]. A polymer of the compound represented by the general formula (I). A light emission element material using these substances. The light emission element in which a light emission layer or a plurality of organic compound layers containing a light emission layer are formed, where at least one layer contains a polymer produced by polymerizing a monomer having a topochemical polymerizing property.
