摘要： An electrochromic polymer is comprised of a repeat unit comprising one or more meta-conjugated linkers (MCLs) and one or more aromatic moieties (Ars). Each of the one or more MCLs is partially conjugated with the one or more Ars at meta positions of the MCLs to form a polymer backbone of the electrochromic polymer. The electrochromic polymer undergoes an optical switching and a color change in an electrochromic device, which shows a high transparency and a high optical contrast.

摘要： Green electrochromic (EC) materials based on thiophene, and a green EC material based on pyrazine are disclosed. A first thiophene derivative (2,3-Di-thiophen-2-yl-thieno[3,4-b]pyrazine), which was previously investigated as a nonlinear optical material, is here disclosed for its use as an EC material and for its incorporation into an EC device. Synthesis of two new thiophene derivatives (2,5-di(thien-2-yl)-3,4-di(2,2,2-trifluoro-ethoxy)-thiophene and 2,5-(2,3-dihydro-thieno[3,4-b][1,4]dioxin-5-yl)-3,4-di(2,2,2-trifluoro-ethoxy)-thiophene), and a new pyrazine derivative (2,3-dibenzyl-5,7-di(thien-2-yl) thieno[3,4-b]pyrazine) are also disclosed, since these materials are all able to selectively change state to appear a green color and can be polymerized to achieve a green EC polymer.

摘要： A soluble donor-acceptor electrochromic polymer (DA-ECP) is prepared that absorbs light throughout at least the majority of the visible range and is essentially black to the human eye when in the neutral state, but is highly transmissive when electrochemically doped. The conjugated polymer has acceptor units separated by sequences of a plurality of donor units. The sequences can be monodispersed or polydispersed. The DA-ECP is prepared by the polycondensation of a plurality of at least one donor-acceptor oligomer (DA-oligomer) that has at least one internal acceptor repeating unit and at least one donor repeating unit on all termini of the oligomer, and optionally, a plurality of at least one donor monomer and/or donor oligomer.
