Abstract: The present application relates to a Michael Addition curable composition, coating composition containing the same and coated article made therefrom. In particular, the Michael Addition curable composition comprises at least one reactive donor capable of providing two or more nucleophilic carbanions; at least one reactive acceptor comprising two or more carbon-carbon double bonds; and at least one catalyst for catalyzing a Michael Addition crosslinking reaction between the at least one reactive donor and the at least one reactive acceptor, wherein the at least one reactive donor comprises at least one branched polyester comprising at least one polyester backbone and at least one —C(O)—CH2—C(O)-moiety; wherein the at least one polyester backbone is derived from an alcohol component comprising at least one alcohol having at least three hydroxyl groups; and wherein the at least one branched polyester has a —C(O)—CH2—C(O)-moiety equivalent of no more than 700 g/mol.

Abstract: Disclosed are an amine-oxide-group-containing conjugated polymer photoelectric material and application thereof. The amine-oxide-group-containing conjugated polymer photoelectric material consists of conjugated main chains and a side chain containing an amine oxide unit, and is applied in an organic photoelectric device. The material has desirable alcohol/water solubility and photoelectric properties, is suitable for making a multi-layer solution for machining a device, and meanwhile can prevent an adverse effect incurred by freely moving counter ions in a common polyelectrolyte to the device. The material may be used as a cathode interface modification layer applied in organic photoelectric devices such as light-emitting and photovoltaic devices, so as to improve performance of the devices.
