On September 1, 2022, Shibuya, Hiromasa; Suk Choi, Yeong; Choi, Taejin; Yun, Sungyoung; Moon, Juhee; Matsuo, Yutaka published an article.Quality Control of 2,4-Di-tert-butylphenol The title of the article was Synthesis of n-type [60]Fullerene Derivatives with Sterically Bulky tert-Butyl Groups for Vacuum Deposition Processes. And the article contained the following:
The thermal stability of [60]fullerene derivatives I (R1 = 4-fluorophenyl, 3,5-difluorophenyl; R2 = H, Me), II (R3 = H, t-Bu; R4 = H; R3R4 = -CH=CH-CH=CH-; R5 = H, Ph, t-Bu) with various bulky substituents for thermal evaporation under vacuum by means of thermogravimetric anal. under reduced and normal pressure was investigate. The sterically bulky groups such as tert-Bu groups of [60]fullerene derivatives I, and II lowered the vacuum deposition temp were founded. Also, isothermal thermogravimetric anal. was performed to examine the long-term thermal stability of the designed compounds under heating conditions. Furthermore, the UV-Vis absorption patterns of the deposited films were investigated. Absorption in the blue wavelength range, which was attributed to intermol. HOMO-LUMO transitions among the MOs of adjacent [60]fullerenes I and II was dramatically modified. These results were associated with the prevention of aggregation among neighboring [60]fullerene by the sterically bulky groups. This concept could contribute to expanding the use of evaporable [60]fullerene derivatives I and II in organic thin-film electronics research fields. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Quality Control of 2,4-Di-tert-butylphenol
