- 20Glass or quartz favour formation of a thin film of aggregated TPPS4 molecules. Clean plastic vials, such as Eppendorf tubes or pipette tips are suitable for manipulating concentrated aqueous solutions of TPPS4. However, care must be taken as some containers are rinsed with detergents which can be chiral, thus biasing as contaminants the J-aggregate formation. A simple test is to shake with distilled water such a plastic container: if foam bubbles are formed than probably detergents were used. On the other hand, caps for containers usually have plasticisers but which are non-chiral and completely water insoluble. To be sure, contact with such caps which are used to prevent solvent evaporation, should be avoided. All our preparations were performed in 10 mL polypropylene test tubes free of detergents. However spectroscopic measurements were conducted in Hellma quartz cells.
