Synthesis and development of oxygen and temperature sensitive phosphorescent paints for sensor applications by using controlled synthetic methods

在许多高科技应用中都需要使用功能性涂料。例如，它们被用于空气动力学风洞实验中，以监测表面上的流动和温度梯度。基于氧和温度敏感探头的双传感器材料的开发，可以应用于低成本的湿化学工艺，如喷涂层或旋涂，具有巨大的技术影响。获得这种功能涂层的一个有希望的途径是将光致发光的氧和温度敏感的过渡金属络合物与具有不同透氧性的各种共聚物巧妙地结合在一起。这种材料设计在传感器技术和成像应用方面提供了有利的前景，这是因为用作指示剂的目标Ir(III)络合物具有明亮和颜色可调的发射。这一联合项目致力于开发智能组合的铱(III)络合物，具有氧封闭和透氧共聚物链段的优化组成，从而能够微调传感器响应。可以预期，该项目将对多通道传感器和具有优异性能的成像应用的改进和高灵敏度材料的设计产生有益的影响。

Functional coatings are required in many high-tech applications. They are, e.g., used in aerodynamic wind-tunnel experiments for monitoring flows and temperature gradients on surfaces. The development of dual sensor materials based on oxygen and temperature sensitive probes that can be applied by low cost, wet-chemical processes such as spray-coating or spin-coating has a great technological impact. A promising avenue to obtain such functional coatings relies on the smart combination of photoluminescent oxygen- and temperature-sensitive transition metal-complexes with various copolymers exhibiting different oxygen permeability. This material design offers favorable perspectives in sensor technology and for imaging applications due to the bright and color-tunable emission of the targeted iridium(III) complexes used as indicators. This joint project addresses the development of smart combinations of iridium(III) complexes with an optimized composition of oxygen blocking and oxygen permeable copolymer segments, enabling a fine-tuning of the sensor response. It can be expected that this project will have a beneficial impact towards the design of improved and highly sensitive materials for multi-channel sensors and imaging applications with outstanding properties.
