Synthesis of Crystalline Phosphine-Graphdiyne with Self-Adaptive p−π Conjugation

Abstract

“Dynamic” behavior materials with high surface activity and the ability of chemical bond conversion are the frontier materials in the field of renewable energy. The outstanding feature of these materials is that they have adaptive electronic properties that external stimuli can adjust. An original discovery in a new crystalline two-dimensional phosphine-graphdiyne (P-GDY) material is described here. Although the p−π conjugation of most trivalent phosphorus π-systems is insignificant because of the pyramidal configuration, the lone pair electrons of phosphorus atoms participate strongly in the delocalization under the influence of the interlayer van der Waals forces in P-GDY. Due to the dynamically reversible nature of noncovalent interactions (p−π conjugation), P-GDY exhibits a specific adaptive behavior and realizes the responsive reversible transport of a lithium ion by regulating p−π interactions. Our findings would provide the potential to develop a new family of responsive materials with tunable structures.

Two-Dimensional Carbon Graphdiyne: Advances in Fundamental and Application Research

“…79 Wang et al synthesized a crystalline 2D phosphine-graphdiyne (P-GDY) material (Figure 5i−l). 80 Experiment results revealed that the p−π conjugation of most trivalent was insignificant, owing to the pyramidal configuration. HRTEM and SEAD images in different crystal orientations indicated the high crystallinity of the P-GDY (Figure 5m−p).…”

One-dimensional benzo[1,2-b:4,5-b′]dithiophene-based graphdiyne for electrochemical adsorption of chloramphenicol

“…20 Another successful strategy has been developed to fabricate two-dimensional (2D) hybrid sp/sp 2 graphdiyne or related carbon rich systems with a 2D structure. [20][21][22][23][24][25][26][27][28] All the above studies have experimentally confirmed the importance of novel carbon allotropes comprising a quantitative content of sp-hybridized carbon and their unusual properties. Compared to sp 2 and sp 3 hybridized carbon, sp carbon shows affinity to certain metal atoms or organic molecules with particular functional groups, which makes carbon material containing sp carbon exhibit broad development space in the fields of selected adsorption, deposition and separation.…”

Design, synthesis, and application of some two-dimensional materials

“…The uniform distribution of heteroatoms plays an important role in regulating the coupling process, aggregation structure, and physical properties of as-prepared products. 81,[104][105][106][107] Due to the different intrinsic characteristics of the doped heteroatoms, there will be quite a different bonding environment around them. Thus, heteroatom doping can effectively adjust the reaction process and adjust the properties of materials.…”
