Alcohol-soluble 2,7-carbazole-1,4-phenylene copolymers PCP-NOH and PCP-EP, comprising surfactant-like diethanolamino and phosphonate end groups on the side chains, respectively, were synthesized and utilized as electron injection layer (EIL) in combinatio

A convergent synthesis of a series of 4,4′-functionalized 1,1′-biisoquinolines via 1-chloro-4-hydroxyisoquinoline and substituted biphenyl- and phenylpyrimidine ethers as building blocks is described. The latter were prepared by Williamson etherification of the respective 4-hydroxybiphenyl and -phenylpyrimidine precursors with dibromoalkanes, allowing variation of the spacer lengths. 1-Chloro-4-hydroxyisoquinoline was obtained from N-phthalimidoglycine ethyl ester through a Gabriel-Colman reaction as a key step. Linkage of the building blocks by etherification in the presence of potassium carbonate gave the isoquinolines, which were submitted to a nickel(II) chloride mediated homocoupling to yield the ligand systems.
