Abstract
The optical properties of a new soluble PPP-type polymer, poly(benzoyl -1,4-phenylene) (PBP), were studied. PBP films show bright blue photol uminescence (PL) with a maximum emission at 433 nm. The PL quantum yie ld of PBP in dilute chloroform solution is approximately 15%. Electrol uminescence (EL) was investigated using PBP as the active layer in sin gle and multilayer LEDs. The EL of all fabricated devices lies in the blue region with a maximum brightness of about 100 Cd/m(2). These resu lts show that PBP might be a promising material for optoelectronic dev ice applications.
