The embodiment of the present disclosure provides a method for preparing a boron dipyrromethene (BODIPY) derivative and an application of the BODIPY derivative. The method comprises: 1) taking BODIPY-1, diphenylacetylene, copper acetate monohydrate, anhydrous sodium carbonate, and metal catalyst, and dispersing the BODIPY-1, the diphenylacetylene, the copper acetate monohydrate, the anhydrous sodium carbonate, and the metal catalyst in an organic solvent for carrying out a cyclization reaction to obtain a cyclization product mixture; 2) rotary evaporating the cyclization product mixture to obtain a concentrated solution of a reaction system; 3) purifying the concentrated solution of the reaction system by a column chromatography, continuing to rotary evaporate a purified product, and then drying a product after the rotary evaporating to obtain a photocatalytic material BODIPY-2.

Metal-organic frameworks are synthesized from either a high concentration synthesis where reaction solutions comprising increased reagent concentrations, or suspensions of reagents which exceed their solubility limit in the reaction solution in a high solids synthesis. In both approaches, the solubility of reagent is maximized by inclusion of a buffer, fixing a nominal pH of the reaction solution to allow metal-organic framework formation. These methods improve yields and scale up of metal-organic frameworks.
