An anti-freeze fluorescent organogel with rapid shape-forming properties for constructing artificial light harvesting systems used in extremely cold environments

Abstract

Using polyvinyl alcohol (PVA) and perylene-3,9-dicarboxylic acid (PDA) as raw materials, a new anti-freeze (-50 ℃) fluorescent organogel with rapid shape-forming (2 h) was synthesised based on a certain proportion...

Construction of an Artificial Sequential Light-Harvesting System and White-Light Material Utilizing Supramolecular Gels

“…In nature, photosynthesis enables plants and photosynthetic bacteria to collect and transfer solar energy. − This process involves the collection and multiple transfers of solar energy in which antenna pigments, such as chlorophyll in chloroplasts, play an essential role. The photosynthetic process prompted researchers to start developing artificial light-harvesting systems (ALHSs) for the efficient collection and transfer of light. − These studies commonly used energy transfer efficiency (Φ ET ) and antenna effect (AE) to evaluate the performance of the ALHS. − Φ ET refers to the quenching rate of the donor after energy transfer, and AE indicates the amplification of the emission intensity of the acceptor after energy transfer from donor to acceptor. In 2015, Wang’s research group successfully constructed an artificial light-capture system with supramolecular polymers based on boron-pyrrole difluoride (BODIPY) derivatives in the organic phase .…”
