A process for deprotecting an organic compound is described, involving the use of an acid to remove an acid-labile protecting group, and a cation scavenger to react with the protecting group once it has been removed. Also described are cation scavengers suitable for use in the processes described herein, as well as a method for preparing a defined monomer sequence polymer. The cation scavenger has the following Formula I: A-B-C−D+ wherein A is a group capable of forming a covalent bond with the acid-labile protecting group once removed from the organic compound; B is absent or is a linking moiety; C− is a negatively charged group; and D+ is a counter ion.

A method for forming a film, comprising the steps of: providing a solution comprising a polyalkylenimine, chloride counterions to protonated sites on the polyalkylenimine, and chloride ions; exchanging bound hydroxide anions from an anion exchange material for the chloride ions yielding released hydroxide anions; increasing pH of the solution, without a correlated sodium ion increase, through reaction of protons in the solution with the released hydroxide anions from the anion exchange material, which partially deprotonates the polyalkylenimine; repeating the steps of exchanging, increasing, and deprotonating until the pH of the solution increases to greater than three; and forming the film from the solution, the film comprising a thickness in a range of 0.1 to 10 μm with a charge density, of protonated sites of the film, of greater than 300 C / in3, the protonated sites associated with counteranions.
