General description
Thieno(3,2-b)thiophene (TT) is an electron rich conjugated polymer that has a quinoidal structure with a narrow band gap. It facilitates a strong intermolecular networking.
Application
TT may be used as conjugated side chains in the synthesis of donor-acceptor copolymers. It finds potential applications in the enhancement of power conversion efficiency (PCE) for organic solar cells.

Four new bis(tpy) unimers with different linkers between the thieno[3,2-b]thiophene-2,5-diyl central unit and terpyridine-4'-yl (tpy) end-groups: no linker (Tt), ethynediyl (TtE), 1,4-phenylene (TtPh) and 2,2'-bithophene-5,5'-diyl (TtB) are prepared, characterized, and assembled with Fe2+ ions to metallo-supramolecular polymers (Fe-MSPs). The Fe-MSP

Multilevel metal interconnects are crucial for the development of large-scale organic integrated circuits. In particular, three-dimensional integrated circuits require a large number of vertical interconnects between layers. Here, we present a novel multilevel metal interconnect scheme that involves solvent-free patterning
