Developing multi-functional materials is crucial to manufacture integrated devices and advanced instruments. However, the development of multi-functional properties is limited because most of the materials can only perform single-phase processing or detection. In this current study blue-emitting, amphiphilic purine-doped and amphiphilic carbon dots (CDs) have been synthesized for the construction of multi-functional materials. These multi-functional CDs (MF-CDs) can form stable dispersions of monodisperse nanoparticles or nanoaggregates in organic/aqueous phase, which endow them with the capability to be either processed or used as detectors/sensors in a variety of solvents. The MF-CDs not only can detect pH, metal cations and the polarity of organic solvents via the change of fluorescent signals in the solution state, but also can be applied in the fields of temperature response and laser-stimulus response in a composite film. As a consequence of the architecture of the MF-CDs composite systems multi-functional characteristics can be realized successfully, which provides a new perspective to develop integrated materials at the nanoscale level.

开发多功能材料对于制造集成设备和先进仪器至关重要。但是，由于大多数材料只能执行单相处理或检测，因此多功能特性的开发受到限制。在当前的研究中，已经合成了发蓝光，两亲性嘌呤掺杂和两亲性碳点（CD），用于构造多功能材料。这些多功能CD（MF-CD）可以在有机/水相中形成稳定的单分散纳米颗粒或纳米聚集体分散体，使其具有在各种溶剂中进行处理或用作检测器/传感器的能力。MF-CD不仅可以通过溶液状态下荧光信号的变化来检测pH值，金属阳离子和有机溶剂的极性，而且还可以应用于复合膜的温度响应和激光刺激响应领域。MF-CDs复合系统的体系结构可以成功实现多功能特性，这为开发纳米级集成材料提供了新的视角。
