Executive Summary : | The increasing demand for electronic devices, such as energy and lighting, necessitates the exploration and synthesis of organic semiconducting materials. Organic materials, including organic chromophores and cocrystals, play a crucial role in these devices by absorbing light and separating electrons. The generation of organic chromophores and their cocrystals has revolutionized the role of organic molecules in material sciences, resulting in one-dimensional (1D) organic crystals with classical intrinsic properties and 2D organic crystals with significant energy transfer properties, making them suitable for photonics applications. However, these organic crystals have limited 2D self-assemblies, making it challenging to design functional organic molecular structures with 2D self-assembly structures. The evolution of organic cocrystals by Wçhler in 1844 using tetrathiafulvalene/7,7,8,8-tetracyanoquinodimethane (TTFTCNQ) has re-attracted attention. The critical problem in this research field is the lack of mechanistic information related to structure-dependent interaction during co-crystallization. The effective path to controlling cocrystallization assembly can be estimated using stoichiometric ratio, controlling molecular stacking mode using substituent effects, crystal phase arrangements, and morphology.
The main aims of the project include synthesizing a new class of luminescent boranil-based derivatives, determining substituent scope, constructing supramolecular self-assembled molecular structures, studying donor-acceptor intermolecular interactions, and examining the effect of surfactants in mediated reaction paths and 2D self-assembly. This will provide easy access to the new class of organic chromophores and stimulate the growth of 2D-supramolecular architectures. |
