Abstract |
: |
Recently, there has been a great deal of scientific interest in the concept of aggregation-induced emission (AIE), which is crucial to the study of organic luminogens. Numerous AIE-active compounds have been described because to their distinctive luminescent characteristic of enhanced emission in the aggregate state and their prospective uses, such as organic light-emitting diodes (OLEDs), fluorescent sensors, molecular probes, photovoltaic cells, and biological applications. A lot of AIE active molecules were designed and synthesized. Among of these molecules designed and synthesized imidazole derivatives. Also, mechanofluorochromic (MFC) materials, in which their solid-state fluorescence colors display noticeable changes in response to external force, have gained great attention. The MFC innovative materials have shown advanced application in different fields, such as mechanosensory, wearable devices, anti-counterfeiting, optical recording, security papers, data storage, and optoelectronics. Organic D-π-A systems have remarkable optical and spectral properties due to their highly polarizable structures resulting from efficient ICT from the donor to the acceptor. The majority of the newly produced mechanofluorochromic (MFC) materials as ICT dyes with AIEactive features and among them imidazole-based donor-π-acceptor. This thesis presents the synthesis, characterization, and investigating of AIE and reversible mechanofluorochromism (MFC) of new imidazole-based donor-π-acceptor dyes. |
