A low band gap silicon-containing polymer

摘要

Recently, the design and synthesis of low band gapnpolymers have attracted a great deal of attention duento their intrinsic electrical and optical properties asncompared to most conjugated polymers [1, 2]. Generally,npowerful approaches to low band gap systems are thatnone is the introduction of quinoid character into thenaromatic conjugated polymer backbone and another isnthe alternation arrangement of strong aromatic donor andnacceptor moieties along the polymer main chain [3–7].
