Congratulations to Dr. Cheng-Wei Lin and alumna Dr. Xueying Chang for their recent Account on aniline oligomers, showing how their well-defined molecular structures enable precise control over doping behavior, crystal growth, and functional properties. By treating aniline oligomers as tunable small molecules, the study demonstrates new insights into redox chemistry, nanostructure formation, surface functionalization, and applications ranging from membranes to long-cycle-life supercapacitor electrodes, revealing advantages that surpass traditional conducting polymers.
