TL;DR: In this paper, a fully conjugated para-phenylene ladder polymer (P1) and the alternating copolymers {2,7-[9,9-bis(2-ethylhexyl)fluorene]-5,5′-(2,2′-bithiophene)} (P3) and { 2,7]-9, 9-dioctylfluorene]5, 5′(2, 2,2,bithiohene) (P4) have been prepared via metal-mediated cross-coupling

TL;DR: Internal photocurrent quantum yields near 100% can be obtained from the separation of loosely bound geminate pairs when sufficiently large electric fields are applied to organic heterojunctions.

TL;DR: Arylene ladder polymers incorporating conjugated 1,5- and 2,6-naphthylene building blocks were synthesized in this article using a palladium-mediated Suzuki-type crosscoupling reaction using both conventional and microwave heating.

TL;DR: In this paper, transient and steady-state charge transport measurements have been conducted on the prototype donor/acceptor copolymer poly[2,7-(9,9-dialkyl-fluorene)-alt-5,5-(4,7'-di-2-thienyl-2,1,3'-benzothiadiazole)] (PFTBTT).

TL;DR: In this article, a series of linear, high-molecular-weight polymers were synthesized by one-pot, metal-free superacid-catalyzed reaction of isatins (1a−d) with linear, nonactivated, multiring aromatic hydrocarbons: biphenyl (A), pterphenyl (B), p-quaterphenyl(C), 2-(4-biphenylyl)-6-phenylbenzoxazole (D), 9H-fluorene (E), 9,9-dim
