Abstract
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). Detailedly, DPA and BACT were connected together through dative B ← N bonds to form zigzag polymer chains, and the neighboring chains interacted with each other through hydrogen bonds to form a pseudo-two-dimensional structure. The observed significant decrease in the fluorescence intensity of CityU-30 compared to that of 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 research studies.
