Multistage side-chain conjugated polymers (CPs) have a conjugated backbone from a multiplicity of repeating unit where at least one of the repeating units has a multistage side-chain. The repeating unit has a conjugated backbone portion and a multistage side-chain, which has one or more responsive functionalities. Responsive functionalities include a photo- or thermal-cleavable portion connected by a first linker between the backbone portion and the cleavable portion, and a chemically activatable solubilizing portion having an activatable functionality that can undergo a chemical reaction to provide aqueous solubility. The multistage side-chain CP is prepared in an organic solution and converted to an aqueous soluble activated multistage side-chain CP for deposited on a substrate. Upon cleavage, a multistage side-chain residue is liberated and removed from an insoluble core CP film that can be part of an organic electronic device.
