Abstract:
Fluorescent organic materials that exhibit unique aggregation-induced emission have been utilized for various applications, including white light emission (WLE). The materials typically rely on composite designs involving a mixture of compounds emitting at different wavelengths of light. To overcome the limitations offered by the design of such composite mixtures, tremendous efforts were also emphasized in developing single-molecule substrates that emit white light. The white light by either method is typically controlled by the solvent polarity, energy and charge transfer, host-guest interactions, gelation, or embedding in the polymer or organic frameworks. This article briefly reviews various molecules exhibiting aggregation-induced emission behavior and emitting white light.
