Abstract
A polymer, including alkyl substituted poly(2,2 '-bipyridine-5,5 '-diyl) having chemical formulae as follows: ##STR1## wherein R and R' are H or an alkyl group having not less than 1 carbon atom, except that at least one of R and R' is an alkyl group having not less than 3 carbons, `n` is a degree of polymerization and is not less than 10. The polymer may be used as a material for a device selected from the group consisting of a battery, an electrochromic device, an electronic device, a n-type conductor and an electroluminescence device, and may be used as polymer ligand to a metal element.
