Acetic acid is an inexpensive and environmentally friendly solvent for facile, clean and high-yielding aryl amination of cyanuric chloride with aromatic amines, including nitroanilines. Aryl amination in acetic acid medium and isolation protocol are greatly simplified as compared to previously reported procedures. Under proper conditions, it is possible to attach the same or different aniline residues
A rheology modifier/hair styling resin which is a crosslinked, linear poly(vinyl amide/polymerizable carboxylic acid) copolymer exhibits advantageous hair care properties of high viscosity and long-lasting curl retention.
The most important parameter of organic molecules for energy harvesting application focuses mainly on their band gap (HOMO-LUMO). In this report, we synthesized differently substituted 1,3,5-triazine based organic molecule which on future processing can be used in organic electronics like solar cells and OLED's. The energy gap of the synthesized novel analogue was calculated using cyclic voltammetry, UV-Visible spectroscopy and compared with density functional theory (DFT) studies.
