Article Synopsis
- The study focuses on the synthesis of two oligophenyleneimine pentamers, DAFCHO and FDACHO, which contain terminal aldehydes, using mechanochemistry methods and various diamines.*
-
- The compounds were characterized using spectroscopy techniques (¹H and C-NMR, FT-IR, mass spectrometry) and displayed interesting photochromic properties in chloroform when exposed to sunlight, with notable energy band gap values measured.*
-
- Electrochemical studies revealed their potential as organic semiconductors, with HOMO and LUMO values indicating favorable electronic properties, and findings were further supported by Density Functional Theory (DFT) calculations.*
Article Synopsis
- Two phenyleneimine oligomers, OIC1MS and OIC2MS, were synthesized using both traditional and mechanochemical methods.
- These compounds were characterized using techniques like FT-IR and NMR, and their optical properties were examined with UV-visible spectroscopy, revealing that OIC2MS has notable photochromic characteristics.
- Additionally, their structural and electronic properties were studied using TD-DFT, indicating that mechanosynthesis is a highly effective approach for creating these tetraimines.
