Photochemical reaction technology is a process technology that relies on the absorption of light energy by a reactive system for chemical synthesis reactions. CD BioSciences-GreenChemistry's cutting-edge photochemical reaction technology platform uses light as a pen to draw a blueprint for green chemistry, leading clients into a new era of innovative synthesis. We help our clients achieve excellence in synthesizing complex molecules, efficient catalysis, and environmentally friendly processes, making every ray of light a driving force for sustainable development.
Photochemical reaction refers to a chemical reaction triggered by the absorption of photon energy by the reactants under visible or ultraviolet light and the energy level jump of electrons inside the reactants, which leads to the change of charge distribution and chemical bonding properties in molecules. Compared with the traditional thermochemical reaction, photochemistry can mostly occur at room temperature or low temperature, which is characterized by energy saving and a green economy. In addition, another major feature of photochemical reactions is that the reaction is mild without the need to protect the groups, which greatly reduces the difficulty of compound synthesis. Therefore, in some conventional synthesis inserting a step photochemical reaction can greatly shorten the synthetic route, for organic synthesis provides an efficient and safe synthetic method.

Photo-oxidation Design and Optimization
Based on the characteristics of the oxidation reaction, we select the most suitable type of light source and wavelength to catalyze the oxidation reaction under specific conditions (e.g., light intensity, reaction temperature, and time). To ensure the efficient operation of the photo-oxidation process, we also provide services such as catalyst selection, substrate preparation, and optimization of the reaction medium.
Photo-oxidation Reduction Design and Optimization
We design efficient photocatalytic redox reaction systems by combining reaction properties and objectives. We employ novel photosensitizers or photocatalytic systems to improve the selectivity and efficiency of the redox reaction and optimize the key parameters by adjusting the light intensity, temperature, and reaction time experimentally to develop an efficient and sustainable photocatalytic redox reaction process.
Photocatalytic Fluorination Design and Optimization
We provide the appropriate type of light source to determine the maximized catalytic efficiency. The optimal fluorination reaction is designed by adjusting the solvent type, reaction temperature, fluorination reagent, and substrate concentration to achieve the best reaction results. Next, the process of photocatalytic fluorination reaction is validated in a larger-scale reaction system to ensure its applicability in large-scale production.
Photocatalytic Nanoparticle Manufacturing Service
Based on the properties of the target nanoparticles, we select suitable materials and chemical precursors for composition and structure design to meet the photocatalytic reaction requirements. By adjusting the type of light source, reaction temperature, and time, we achieve the optimal synthesis of nanoparticles. In addition, we provide optimization of precursor solution ratios to ensure consistent nanoparticle size and morphology.
