Molecular self-assembled chemosensors and their arrays

Herein, we propose approaches of self-assembled chemosensors only using off-the-shelf reagents to easily obtain various chemosensors without organic synthesis. The concept of self-assembled chemosensors comprising off-the-shelf reagents with water solubility realizes not only the easy tuning of optical sensing properties but also chemical sensing in real samples. We summarize the comprehensive sensing applications using the facile self-assembled chemosensors and their arrays combined with pattern recognition techniques, and the usability of off-the-shelf reagents in analytical chemistry.
