Poly(p-phenylene vinylene) (PPV) is known to be a typical π-conjugated polymer and used as a commodity platform for constructing optoelectronic organic devices because of superior optical and material properties. PPV derivatives generally show a large degree of light absorption and intense emission in the visible region; meanwhile, very few examples have been reported to offer near-IR (NIR) absorptive and emissive PPV derivatives In this study, we designed and synthesized a novel PPV derivative, named BAz-PPV, containing boron-fused N=N double bond units in the main chain. BAz-PPV showed intense NIR absorption and emission (λabs = 702 nm, λPL = 760 nm, and ΦPL = 2.0% in diluted toluene). This polymer had a narrow energy band gap because of not only extension of main chain π-conjugation over 50 monomer units but also stabilization of the energy level of the LUMO. Moreover, the polymer shows high stability toward photodegradation and sufficient carrier-transport ability for the applications in organic semiconducting devices. Advantages of the introduction of the N=N double bond to main-chain conjugation followed by boron coordination for the development of NIR materials are demonstrated in this manuscript. The experimental part of the paper was very detailed, including the reaction process of Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3Formula: C51H42O3Pd2)
Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3) is used in the preparation of semiconducting polymers processed from nonchlorinated solvents into high performance thin film transistors.Formula: C51H42O3Pd2 It is also used in the synthesis of polymer bulk-heterojunction solar sells as a semiconductor.
