These gels utilize weak intermolecular interactions that can be manipulated by light stimulation. Photoresponsivity is achieved by incorporating chromophoric units into the gelator molecules. Based on the type of the photoresponsive unit, the gels can undergo different kinds of photoreactions upon light irradiation, causing changes in the gel properties. The literature part focuses on useful photoreactions that can be exploited in photoresponsive LMWGs. In addition, the properties, design, characterization, and applications of these gels are discussed.\nThe experimental part deals with the synthesis of possible photocleavable peptide-based LMWGs functionalized with boron dipyrromethene (BODIPY). The BODIPY moiety was aimed at being linked to a peptide-based gelator via a carbamate bond. As a result of several attempts, one possible product was obtained. However, based on the NMR spectroscopy and HR-MS measurements, the formation of the desired compound could not be fully proven.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.abstract", "value": "T\u00e4m\u00e4 pro gradu-tutkielma k\u00e4sittelee valoresponsiivisia alhaisen molekyylipainon geelej\u00e4 (low molecular weight gels, LMWGs), jotka muodostuvat kevyiden gelaattorimolekyylien itsej\u00e4rjest\u00e4ytyess\u00e4.
