    Abstract: A method of producing a polyether polyol that includes reacting a low molecular weight initiator with one or more monomers in the presence of a polymerization catalyst, the low molecular weight initiator having a number average molecular weight of less than 1,000 g/mol and a nominal hydroxyl functionality at least 2, the one or more monomers including at least one selected from propylene oxide and butylene oxide, and the polymerization catalyst being 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, and R3 each includes a same fluoroalkyl-substituted phenyl group, and optional R4 includes a functional group or functional polymer group. The method further includes forming a polyether polyol having a number average molecular weight of greater than the number average molecular weight of the low molecular weight initiator in the presence of the Lewis acid catalyst.

    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 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.
