Resumen:
The photoinduced curingkinetics of bioinspired copolymers Vinylbenzyl Thymine (VBT) and VinylphenylSulfonate (VPS) was studied using fluorescence spectroscopy in combination withmultivariate analysis. Fluorescence spectroscopy enables a detailed descriptionof the curing process of VBT copolymers in real time, combining selectivity,simplicity and sensitivity, without the need of sample pre-treatments, being anadvantage from the green analytical chemistry point of view. Twochemometric strategies were used to decompose the datamatrix generated while monitoring the curing reaction, identifying the evolutionof each species involved in the processin conjunction with the corresponding purespectra. A comprehensive comparisonbetween the developed approaches was performed, clearly highlighting theadvantages and disadvantages of both of them. The use of multivariate analysis appliedto fluorescence spectroscopic data to study curing reactions have several advantages such as no sample pretreatment, no sophisticatedequipment requirement, reduced analysis time and use of non-toxic solvents,among others.
