Introduction to the State Key Laboratory of Fine Chemicals: The State Key Laboratory of Fine Chemicals was established in 1991 by the State Planning Commission with World Bank loans and relying on Dalian University of Technology. The research directions of the laboratory include dyes and their photochemistry, new fine chemical materials, and fine chemicals cleaning and preparation technology. The laboratory has good research equipment and conditions, with an experimental area of ​​more than 7,000 square meters of concentrated space, and more than 80 sets of advanced instruments and equipment such as high-resolution time-of-flight tandem mass spectrometers and single crystal diffractometers. Research platforms for sensitized solar cells, fine polymer materials, fine chemical catalytic technology, and kilogram-scale engineering centers for fine chemicals are under centralized and unified management and dedicated to public use, providing a strong platform support for high-level research work.
