Special Issue Information

Dear Colleagues,

The last decade has witnessed tremendous progress in the emerging frustrated Lewis pair (FLP) chemistry, since the seminal discovery of heterolytic cleavage of dihydrogen by sterically encumbered Lewis acid/base pairs. Thanks to the vigorous and sustained research carried out in this area, FLP chemistry has proved to be a powerful and versatile transition-metal-free strategy for small molecule activations and related catalytic transformations. Subsequent efforts have been devoted to the understanding of fundamental aspects of FLP chemistry and exploiting the reactivity and cooperativity of Lewis pairs to new areas such as polymer synthesis. In this context, the concept of Lewis pair polymerization (LPP)—which utilizes an FLP, a classical Lewis adduct (CLA), or an interacting Lewis pair at the intermediacy between FLP and CLA states—to achieve cooperative monomer activation and chain initiation and/or propagation has been developed to synthesize various types of polymers. The seemingly unlimited tunability of the steric effects and electronic properties of Lewis acids and bases, and therefore the interactions between the resulting Lewis pairs, allows the development of a variety of initiator or catalyst systems that are capable of promoting different types of polymerizations, such as addition polymerization of polar and non-polar vinyl monomers, and ring opening (co)polymerization of heterocyclic monomers. Living and chemoselective LPP processes have also been recently uncovered.

The goal of this special issue is to collect and disseminate some of the significant contributions in the area of polymer synthesis recently enabled by LPP, emphasizing the development of new polymerization reactions rendered by new Lewis pair catalyst/initiator systems, exploration of monomer scopes, and synthesis of polymers with controlled or unique structures. Hence, we cordially invite you to submit your valuable contributions to this special issue on the LPP topic that interfaces with main-group, organometallic, and polymer chemistry, as well as catalytic and green chemistry.

A synthetic method that taps into the facile Lewis base (LB)→Lewis acid (LA) adduct forming reaction between the semiconducting polymeric LB and all carbon LA C60 for the construction of covalently linked donor-acceptor dyads and brush polymer of dyads is reported. The polymeric LB is built on poly(3-hexylthiophene) (P3HT) macromers containing either an alkyl or vinyl imidazolium end group that can be readily converted into the N-heterocyclic carbene (NHC) LB site, while the brush polymer architecture is conveniently constructed via radical polymerization of the macromer P3HT with the vinyl imidazolium chain end. Simply mixing of such donor polymeric LB with C60 rapidly creates linked P3HT-C60 dyads and brush polymer of dyads in which C60 is covalently linked to the NHC junction connecting the vinyl polymer main chain and the brush P3HT side chains. Thermal behaviors, electronic absorption and emission properties of the resulting P3HT-C60 dyads and brush polymer of dyads have been investigated. The results show that a change of the topology of the P3HT-C60 dyad from linear to brush architecture enhances the crystallinity and Tm of the P3HT domain and, along with other findings, they indicate that the brush polymer architecture of donor-acceptor domains provides a promising approach to improve performances of polymer-based solar cells.
