摘要

Scientists have developed techniques for synthesizing and characterizing many new materials includ-ing conjugated small molecules, polymers and gold particles protected by conjugated organic chro-mophores for testing specific sensing properties in the past decade. Still, the design and synthesis or supermolecular systems fabrication of novel materials with controlled sensing properties is a signifi-cant and ongoing challenge within nanoscience and nanotechnology. Recently, our group has suc-cessfully constructed a series of chemosensors using small organic molecules, conjugated polymersand gold nanoparticles for real-time detection of specific analytes. The chemosensors show high se-lectivity and sensitivity in the detection of cations and biologic analytes and thus are potentially promising for applications in sensing assay system. In this review, recent sutdies on the design, syn-thesis and photo-physical properties of novel materials and construct of chemosensors are summa-rized with an emphasis on the development in our groups in recent years.
