A Covalent Organic Polymer Containing Dative B←N Bonds： Synthesis, Single Crystal Structure, and Physical Properties
Dative boron←nitrogen (B←N) bonds are important in the construction of crystalline covalent organic polymers/frameworks (COPs/COFs). Herein, 9,10-di(4-pyridyl)anthracene (DPA) and 1,4-bis(benzodioxaborolane)benzene (BACT) were employed as building blocks to prepare single crystals of a functional COP (CityU-30). Detailly, DPA and BACT were connected together through dative B←N bonds to form zigzag polymer chains, and the neighboring chains were interacted with each other through hydrogen bonds to form a pseudo-two-dimensional chain structure. The observed significant decrease in fluorescence intensity of CityU-30 compared to DPA indicates a pronounced photothermal effect in CityU-30. This research reveals the crucial role of B←N bonds in designing innovative COPs and guides future materials researches.
