The language is not concise enough to read. There are instances of wrongly used words or phrases, badly constructed sentences, grammatical errors, and spelling mistakes, such as "The introduction of donative elecrton group can increase the HOMO and LUMO energy levels of the title terbium complexes, but the result of introduction of electrophilic group was just opposite", "Rare earth complexes have been attracted significant attention about their fluorescent broad applications in medicinal chemistry , material chemistry  and biochemistry  due to unique physical and chemical properties of rare earth ions", "Meanwhile, pyrazolone and its derivatives, especially 4-acyl pyrazolone, are an important heterocyclic compounds containing N, O atoms and can be used as chelating agent, which have attracted considerable scientific and applied interest in pharmaceutical and biological reagents, metallurgy, dyes, luminescent materials", "Molar conductivity of the complexes in N,N'-dimethylformamide (DMF) were measured at room temperature with an DDS-12A digital direct reading conductivity meter", "Chloroacetic acid (0.04 mol, 3.78 g) was dissolved in 12 mL distilled water in a 50 mL beaker, then 10 mL of 25% sodium hydroxide solution was added dropwise obtained sodium chloroacetate solution", "The solid was filtered and recrystallized from ethanol obtain white crystals, and dried under vacuum to get phenoxyacetic acid 1'a", "The synthesis procedure of the compounds 3'a~g is similar, so only the 2-phenoxyacetohydrazide 3'a has been selected for illustration"
Please check the manuscript carefully and thoroughly to refine the language. Please do not revise only the samples indicated in the comments, which are highlighted as serious problems.
