It began in 1869, and today we have 118 elements listed in the Periodic table, thanks to Mendeleev's work. Carbon, hydrogen, oxygen, and nitrogen are elements presented in many organic compounds. Some of them can exhibit photophysical and photochemical properties. Herein, we proposed an easy to make an experiment in chemistry classes to connect both subjects, periodic table and photochemistry, through periodic tables made of fluorescent jellies. A sheet of PET‐G was heated and put over the periodic table mold made in a 3D‐printing to produce the form used in this work. Quinine and vitamin B2, from tonic water and vitamin supplement, respectively, were the fluorescent compounds selected to be in the gelification process to give the jelly fluorescence. The light source was a black light lamp. This work allowed for the discussion of photophysics and photochemistry concepts, 3D‐printing process, gelification, and the International Year of the Periodic Table of Chemical Elements—IYPT2019—with undergraduate students without the use of expensive reagents or equipment.

从元素周期表到带有荧光果冻的光化学：国际化学元素周期表年的食品科学庆典

它始于1869年，由于门捷列夫的工作，今天我们在元素周期表中列出了118个元素。碳，氢，氧和氮是许多有机化合物中存在的元素。它们中的一些可以表现出光物理和光化学性质。在这里，我们提出了一种易于进行的化学班级实验，通过荧光果冻制成的周期表来连接周期表和光化学这两个主题。将一片PET‐G加热并放在3D打印制成的元素周期表模具上，以生产用于此工作的表格。奎宁和维生素B2（分别来自滋补水和维生素补充剂）是在胶凝过程中选择的荧光化合物，可赋予果冻荧光。光源是黑灯。
