Abstract: The present invention relates to a charge transporting semi-conducting material comprising: a) at least one electrical dopant, and b) a branched or cross-linked charge-transporting polymer comprising cyclobutenone cross-linking units of at least one of the general formulae la and/or lb, wherein aa) Pol1, Pol2, Pol3 and Pol4 are independently selected chains of the charge-transporting polymer, bb) X1, X2, X3, and X4 are independently selected optional spacer units or, independently, represent direct bonding of Pol1, Pol2, Pol3 and Pol4 chains to the cyclobutenone ring, cc) Z1, Z2, Z3, and Z4 are independently selected from H, halogen or a carbon-containing group; the charge transporting semi-conducting material being obtainable by a process comprising: i) providing a solution containing aaa) at least one precursor charge transporting compound comprising at least one covalently attacked alkenyloxy group having generic formula II wherein X is an optional spacer which is further linked to a charge transporting st

Abstract: The present invention relates to a charge transporting semi-conducting material. The charge transporting semi-conducting material may include optionally at least one electrical dopant, and a branched or cross-linked charge transporting polymer that includes 1,2,3-triazole cross-linking units of at least one of the general formulae Ia and/or Ib herein. The charge transporting polymer can include ethylene building units substituted with at least one pending side group including a conjugated system of delocalized electrons. Also provided herein are processes for obtaining the charge transporting semi-conducting material.
