Abstract (en)

[origin: FR2780979A1] The invention concerns a novel type of copolymer emitting in green derived from N-(2,5 di tertbutyl phenyl naphthalamide). Said materials are particularly useful for making electroluminescent diodes owing to the chromophoric groups of the phenyl-tBu type which increases the efficiency of photoluminescence.
