“…Meanwhile, due to cost efficient concern in industrial production, approaches of quantitative analysis of the composition ratio of reaction systems that are convenient and inexpensive were wildly studied. [1][2][3][4][5] Conventional quantitative analysis methods include Gas/liquid chromatography, 6,7 Nuclear magnetic resonance, 8 Raman spectroscopy, 9 Ultraviolet-visible (UV-Vis) absorption spectroscopy, [10][11][12][13] etc. Among these methods, the cost of UV-Vis absorption spectroscopy is quite low, because the equipment itself is less pricey then others, and relatively easier to maintain or operate.…”

Determination of the Mono and Dibromo Derivatives Ratio Resulting from Semiconductor Bromination Using Ultraviolet-visible Absorption Spectroscopy and Gaussian Peak Fitting

et al. 2020

The chemical-industrial production of organic semiconductor urgently needs a cheap and fast approach to determine the components' proportion of the reaction system. In this paper, the Gaussian peak fitting method was applied to process monobromo and dibromo substituted perylene diimide mixed solutions' ultraviolet-visible absorption curves. The functional relationship formula between the peak intensity ratio and the component ratio is then concluded. Finally, the field experiment of perylene imide brominating reaction can be used to confirm such formula is able to calculate the proportion of ingredients in the synthesis reaction solution system accurately.
