A new soluble triphenylamine-based conjugated polymer, poly [N-(4′-butylphenyl) imino (1, 1′∶ 4′, 1 ″-terphenyl-4′ 4 ″-ylene)],(PBPITP), has been synthesized, which emits blue photoluminescence (PL) with high absolute PL quantum efficiency (45±3%) but exhibits red electroluminescence (red shifted by as much as 157 nm from the PL spectrum).
