Insights into the anion effect on the self assembly of perylene bisimide diimidazolium salts

摘要: Abstract We studied how changing the anion affects self-assembly of three diimidazolium salts bearing a perylene bisimide spacer. In particular we used [BF 4 − ] and [NTf 2 based together with mixed salt both [I anions. Thermal as well concentration temperature dependent spectroscopic investigations revealed that impacts on solid state solution aggregation, leading to articulate thermotropic behaviors contrasting solvent effects, respectively. also electrochemical behavior verify if alters redox properties salts. Finally, different anions lead very aggregate morphologies, evidenced by SEM TEM measurements.
