Abstract

Development of easy and efficient sensing tool for instant detection of various organic amines in aqueous media has prime significance. In this context, hollow spherical H-aggregates of pyrazine derivative bearing terminal acetyl groups were demonstrated as a reaction-based vapor phase sensing tool for organic amines. The aggregates displayed ratiometric fluorescence behavior toward aliphatic amines with a detection limit at nanomolar concentrations with concomitant self-assembly modulation from spherical H-aggregates to rod-shaped J-aggregates. Surprisingly, in the presence of p-nitroaniline remarkable quenching response was observed among various aromatic amines, which is attributed to the inner filter effect and energy transfer. Furthermore, a portable efficient tool for sensing various organic amines was constructed using the aggregates, demonstrating the practical applicability of this approach. This work will provide straightforward way for designing multifunctional self-assemblies for efficient selective behavior toward various organic amines in the ground water bodies.
