I found the field of Polymer Science very interesting. Saw the article Study on the effect of different amounts of hydroxyl and tert-butyl substituted triphenylpyridine units on the properties of polyimide published in 2020.0. Formula: C8H7NO3, Reprint Addresses Wang, YH (corresponding author), Sichuan Univ, Coll Polymer Sci & Engn, State Key Lab Polymer Mat Engn, Chengdu 610065, Peoples R China.. The CAS is 100-19-6. Through research, I have a further understanding and discovery of 1-(4-Nitrophenyl)ethanone
Four triphenylpyridine diamines with different substituent structure were successfully synthesized and polymerized to obtained polyimides (PIs) via one-step. The diamines and PIs were characterized by FTIR and H-1-NMR spectra. The aggregated structure of PIs was amorphous by wide angle X-ray diffraction test. The structure of the substituent had an important influence on the properties of PI (such as solubility, thermal stability, optical and mechanical properties). The introduction of tert-butyl group could reduce the solubility in non-polar solvent of PI. In addition, the introduction of hydroxyl group alone could increase the solubility in polar solvent of polymer due to the large polarity of the hydroxyl groups. All PIs exhibited high thermal stability and heat resistance, but the introduction of too much tert-butyl group reduced the thermal stability of PI. The introduction of tert-butyl group could effectively improve the optical properties of PIs. The maximum transmittance of PIs was above 85% (87.2-90.3%).
