摘　　要：由于荧光有机小分子纳米材料在有机电子和生物传感方面具有良好的潜在应用,已逐渐成为有机纳米材料研究的一个热点。本文综述了荧光有机小分子纳米材料的最新研究进展,重点介绍了制备荧光有机小分子纳米材料的多种合成方法,这些方法主要包括再沉淀法、离子缔合法、自组装法、微乳液法、激光烧蚀法、吸附剂辅助物理气相沉积法。本文简要概括了这几种合成方法的优缺点,另外还比较了不同合成方法所制备材料的光电物理性质,并对其在有机光电器件、化学生物传感和生物成像等领域的应用进行了阐述。Fluorescent organic small molecular nanomaterials, due to their excellence performance in organic electronics and biological sensing, have attracted more and more attention in the fields of chemistry, materials, biology, and so on. In the past years, significant advances in both the experimental and theoretical fronts have been made for the nanomaterials and nanotechnology. However, compared with fluorescent inorganic quantum dots or polymer nanoparticles, fluorescent organic nanoparticles（FONs） which based on π-conjugated systems, are becoming more and more important to bio-imaging, drug carriers and optoelectronic, since the wider variability and flexibility in materials synthesis and nanoparticles preparation of organic molecules. This paper systematically introduces the recent research developments of the design, synthesis, photophysical properties and application of fluorescent organic small molecular nanomaterials. The highlights of this paper are the preparation methods of fluorescent organic small molecular nanomaterials, such as reprecipitation method, ion association method, self-assembly method, micro-emulsion method, laser fabrication method, adsorbent assisted physical vapor deposition method. We briefly conclude the advantages and disadvantages of the above-mentioned synthetic methods. In addition, we also compare the properties of the fluorescent organic small molecular nanomaterials synthesized by different method, and give a brief introduction to their application on organic optoelectronic devices, chemical and biological sensing, bio-imaging and other fields.
