Construction of Different Cyanine Dye Supramolecular Aggregates Induced by Rare Earth Ions
CHEMISTRYSELECT(2022)
Abstract
In recent years, the assembly of cyanine dye supramolecular aggregates has been a very important task because its photophysical and photochemical properties are widely used in many scientific fields, such as, materials, biomedical and industrial. In this work, H- and J-aggregates of cyanine dyes were constructed under controllable conditions, and a simple method was developed to achieve cycle induction around these aggregates which induced by rare earth ions, and the process can be repeated for many cycles. Assembly and circulation induce these aggregates to be easy to manipulate and identify, which can be directly observed with the naked eye. This simple supramolecular assembly provides another direction in the field of sensors, while bringing a new idea to the control of supramolecular aggregates.
