Optical Sensing and Energy Transfer in Luminescent and Conductive COORNET Mixed-Matrix Membranes

该联合提案的目的是研究发光配位网络（COORNET）和发光SURMOF薄膜中的基本化学性质和能量转移，以及将两者嵌入聚合物膜（包括导电聚合物基质）中。除了分析调查，模拟和建模的能量传递机制将被执行。此外，COORNETs/SURMOFs/复合材料与相关大气气体水分和氧气的相互作用所伴随的物理过程将进行比较研究，因为传感器通过能量转移到分析物或从分析物的发光调制读出作为主要的传感器功能。COORNET/SURMOF发光的氧和水敏感性应通过将其嵌入有机聚合物薄膜中进行控制、调制和利用，因为COORNET/SURMOF嵌入聚合物薄膜会影响生物物理参数（过程、强度、途径和机制中的能量转移、寿命和功效）。因此，该项目通过机械研究和物理性质的调制来解决基础科学问题。这将导致更好地理解所涉及的过程，包括能量转移及其用于传感的属性调制的性质。此外，该项目还有助于COORNET成型的基本方面，并解决了COORNET/SURMOF-聚合物相容性，化学稳定性和聚合物渗透性等参数。所有这些都与小分子的传感/检测有关。因此，复合材料的目标是在稳定性、处理和长期监测方面超过经典复合物和散装COORNET，同时保持发光传感过程的一般灵敏度。通过将导电聚合物与发光COORNET和SURMOFs相结合，将开发出新的光电子元件和器件，从新的传感器到新的基于MOF的电致发光器件。电致发光构成配位化学的主要成就。

The objective of this joint proposal is to study the fundamental photophysical-properties and energy transfer in luminescent coordination networks (COORNETs) and in luminescent SURMOF thin films as well as the embedding of both into polymer membranes including conductive polymer matrixes. In addition to analytical investigations, simulation and modeling of energy transfer mechanisms will be performed. Furthermore, the photophysical processes accompanying the interaction of COORNETs/SURMOFs/composites with the relevant atmospheric gases moisture and oxygen will be investigated in comparison, as a sensor read out by modulation of the luminescence by energy transfer to or from analytes acts as the main sensor function. Oxygen and water sensitivity of COORNET/SURMOF luminescence shall be controlled, modulated and utilized by embedding them in organic polymer films, as photophysical parameters (processes, intensity, energy transfer in pathways and mechanism, lifetimes and efficacy) can be affected by such embedding of COORNETs/SURMOFs into polymer films. Thereby, the project addresses fundamental science by mechanistic investigation and modulation of photophysical properties. This will lead to a better understanding of the processes involved including energy transfer and its nature for the property modulation used for sensing. Furthermore, the project also contributes to the fundamental aspect of COORNET shaping and addresses parameters such as COORNET/SURMOF-polymer compatibility, chemical stability and polymer permeability. All of them are relevant for the sensing/detection of small molecules. Thereby, composites are aimed at that exceed classic complexes and the bulk COORNETs in stability, handling and long-term monitoring while retaining the general sensitivity of the luminescence sensing process. By combining conductive polymers with luminescent COORNETs and SURMOFs, novel optoelectronic components and devices shall be developed ranging from new sensors to novel MOF based electroluminescence devices. Electro¬luminescence constitutes a major achievement for coordination chemistry.
