Protic organic solvents
WebbOrganic solvents like benzene, ether, and chloroform are neither protic nor strongly polar. Because they are non-polar solvents which stabilizes neither the nucleophile nor the transition state, ΔG ‡ is therefore higher in non-polar solvents and the reaction rate is slower. Benzene, ether, and chloroform are in this category.

The zwitterionic nature of the polymers renders them soluble in and processable from polar, protic solvents to form semiconducting films that are not doped. Webb16 okt. 2024 · Contrary to polar-aprotic solvents (think DMF, DMSO) eventually leading to «naked ions», polar-protic solvents (like ethanol, methanol, water) may weakly interact with these ions; similar to a Lewis acid/base reaction, they stabilize the ions to stay in proximity to each other as an ion pair.
