Synthesis and optical properties of novel blue fluorescent conjugated polymers

Abstract

In the present paper we describe new approaches towards the synthesis of conjugated polymers with defined conjugation length, resulting in a blue or green fluorescence. The new approach reported here is to use 1,3-phenylene (type 1) and 10,10′-bianthrylene (type 2) bridges of conjugated segments such as stilbenes and thiophenes which can easily be varied to further change the optical properties.
