Chiral Flame Retardant Materials: Design, Synthesis and Study of Chirality-Flame Retardancy Relationship between the (R)-Enantiomer and (S)-Enantiomer
Synthetic polymers are widely used in household appliances, cables, wires, electric devices, transportation, construction materials, etc. However, in air condition most polymers are flammable and easy to burn under a relatively high temperature or in the presence of open fire. In many cases, improving flame retardancy of polymers is very important to reduce potential fire risks. Flame retardant materials are extremely important additives in a wide variety of polymeric materials. In decades, versatile phosphorus-containing compounds have been widely used as flame retardants for polymers due to their high efficiency and low toxicity. Moreover,organophosphorus flame retardants have the effect of plasticizing, which can improve flexibility and mechanical strength of polymer materials in the forming process. Thus, to develop late-model organophosphorus flame retardant still is the hot research in current polymer science. Chirality is one of the basic attributes of nature. In the field of material science, using optically pure chiral compounds to study the distinctive properties and functions that compared with the corresponding racemic compounds is still in the embryonic stage but develop rapidly. However, to date, systematically utilize optically pure chiral compounds as flame retardant materials and explore the chirality-flame retardancy relationship between the (R)-enantiomer and (S)-enantiomer of chiral flame retardants have not been reported. The main objective of this innovative work is to use optically pure chiral compounds as flame retardants to develop new generation flame retardant polymer composites. In this project, we designed and synthesized a series of chiral phosphorus-containing compounds as flame retardants for epoxy resin, especially to understand the chirality effect towards flame retardancy between the (R)-enantiomer and (S)-enantiomer of chiral flame retardant. This study will give more insights on developing new generation flame retardants.

Project objective
The development of new strategy to study flame retardant polymers is an exceptionally important area of current research in Material Science and Engineering field since the fire safety of materials is extremely important to the whole society. So far, very seldom study focuses on the chiral flame retardant materials, especially almost no systematic study on exploring the different flame retardancy between (R)-enantiomer and (S)-enantiomer of chiral flame retardant materials. The main objective of this innovative work is to use optically pure chiral compounds to develop new generation flame retardant polymer nanocomposites by combining (R)- or (S)-enantiomer of chiral flame retardant materials into polymeric matrices. In this work, optically pure chiral compounds are employed to develop flame retardant polymer nanocomposites for the first time. The eco-friendly, economical, easily prepared and functionalized chiral BINOL phosphates are chosen as the chiral flame retardant. By introducing functional groups into the BINOL phosphates, it can be combined with polymeric matrices via chemical interaction to construct polymer nanocomposites. Moreover, incorporating ferrocene unit as synergistic agent into the BINOL phosphates, the resulting multifunctional flame retardants to polymer nanocomposites will have advantages including mechanical reinforcement, enhanced thermal stability and excellent flame retardancy and smoke suppression properties, simultaneously. More significantly, chirality-flame retardancy relationship between the (R)-enantiomer and (S)-enantiomer of chiral BINOL phosphates would be systematically investigated to understand the flame retardant mechanisms in a new aspect. The new knowledge and new materials developed in this proposal has the promise to be applied in developing new generation products in the construction, transportation, aerospace industries, in the future.
