The present invention discloses conjugated compounds containing triarylamine structural elements with a general formula AB
m
, wherein A is aryl moiety with or without hetero atom(s), m is integers from 2 to 4, and B is as following:
wherein Ar is aryl moiety. Moreover, the conjugated compounds of the invention are used as hole transport material, hole injection material and/or as host material in organic electroluminescence devices and/or phosphorescence devices, and as hole transport material in solar cells.

Incorporating biphenyls as co-monomers in electron-deficient diketopyrrolopyrrole (DPP) conjugatedpolymers enables widening the optical bandgap to 1.70 eV. Power conversion efficiencies of 3.7-5.7% and high open-circuit voltages of 0.80-0.93 V are obtained in solarcells based on these wide bandgap DPP polymers.

(Ph3P)AuCl was discovered to be a powerful catalyst in the homocoupling of arylboronicacids and potassium aryltrifluoroborates for the synthesis of symmetrical biaryls. The reactions take place under benchtop reaction conditions in 96% EtOH at temperatures between rt and 50 °C with no exclusion of air or humidity, in the presence of F-TEDA (Selectfluor™) as an oxidant. The procedure is very functional
