Construction of aggregation-induced emission monolayer at the air/water interface

Abstract

Construction of aggregation-induced emission monolayer at the air/water interface Kohei Iritani, Department of Applied Chemistry, School of Engineering, Tokyo University of Technology. Organic fluorescent materials using a molecule with aggregation-induced emission (AIE) effect have intense interest due to their potential utilities such as flexible display devices and photovoltaics. For the applications to two-dimensional devices, we purposed the construction of a monolayer formed by a tetraphenylethylene (TPE) derivative as an AIE molecule at the air/water interface. To this end, we synthesized amphiphilic TPE derivatives. We found that the TPE derivative formed a thin film with blue- green emission on the water surface. Moreover, from AFM observations, we confirmed that the transferred film had monolayer thickness.
