    Abstract: A method of producing a polyether polyol includes reacting a low molecular weight initiator with one or more monomers in the presence of a polymerization catalyst, and the low molecular weight initiator has a nominal hydroxyl functionality of at least 2. The one or more monomers includes at least one selected from propylene oxide and butylene oxide. The polymerization catalyst is a Lewis acid catalyst having the general formula M(R1)1(R2)1(R3)1(R4)0 or 1, whereas M is boron, aluminum, indium, bismuth or erbium, R1, R2, R3, and R4 are each independent, R1 includes a fluoroalkyl-substituted phenyl group, R2 includes a fluoroalkyl-substituted phenyl group or a fluoro/chloro-substituted phenyl group, R3 includes a fluoroalkyl-substituted phenyl group or a fluoro/chloro-substituted phenyl group, and optional R4 includes a functional group or functional polymer group, R1 being different from at least one of R2 and R3.

    Abstract: Provided is an organic light-emitting diode comprising a substrate, an anode layer, optionally one or more hole injection layers, one or more hole transport layers, optionally one or more electron blocking layers, an emitting layer, optionally one or more hole blocking layers, optionally one or more electron transport layers, an electron injection layer, and a cathode, wherein either the hole injection layer, or the hole transport layer, or both of the hole injection layer and the hole transport layer, or a layer that functions as both a hole injection layer and a hole transport layer, comprises a polymer that comprises one or more triaryl aminium radical cations having the structure (S1) wherein each of R11, R12, R13, R14, R15, R21, R22, R23, R24, R25, R31, R32, R33, R34, and R35 is independently selected from the group consisting of hydrogen, deuterium halogens, amine groups, hydroxyl groups, sulfonate groups, nitro groups, and organic groups, wherein two or more of R11, R12, R13, R14, R15, R21, R22, R23, R24, R25, R31; R32; R33 R34 and R35 are optionally connected to each other to form a ring structure; wherein one or more of R11, R12, R13, R14, R15, R21, R22, R23, R24, R25, R31, R32, R33, R34, and R35 is covalently bound to the polymer, and wherein A″ is an anion.
