| Projekt: | Photophysical and photoelectric properties of porphyrin-based MOF thin films |
| Zusammenfassung: | In this COORNETs project, we aim to fabricate a novel class of porphyrin based oriented and crystalline MOF thin films. Porphyrin molecule is well recognized in organic photovoltaics (OPV) as an efficient charge carrier. Using the concept of crystalline MOFs on surface we will fabricate porphyrin based thin films on conducting and transparent substrates to study their electrochemical and photophysical properties, respectively. In selected cases these films will be integrated in devices for specific applications, e.g. for photovoltaics. The objectives can be pointed out as follows: i) Synthesis of porphyrin linkers with various functional substituents for tunability of structure and related properties; ii) Fabrication of MOF thin films using those porphyrin linkers on suitable substrates and their photophysical and electrochemical characterizations; iii) Electronic band structure calculation and finding the suitable structure for applications in photovoltaics. Input: The PIs involved in this project have significant amount of prework in collaboration in the recent years. Those works include development of SURMOFs and its characterization techniques, synthesis of various functional porphyrin linkers, calculation of electronic band structures of crystalline thin films, and study of the opto-electronic properties. Such expertise on thin film fabrication, their characterizations and understanding of the opto-electronic properties will be important to achieve the proposed goal. Output: The proposed work will bring up a library of novel class of porphyrin based crystalline and oriented metal-organic thin films. The crystalline films can find applications in photovoltaics and related opto-electronic devices. |
