Triphenylmethyl group
In chemistry, triphenylcarbenium, triphenylmethyl cation, tritylium , or trityl cation is an ion with formula [C19H15] or (C6H5)3C , consisting of a carbon atom with a positive charge connected to three phenyl groups. It is a charged version of the triphenylmethyl radical (C6H5)3C•. The name is often abbreviated to triphenylmethyl or trityl in salts, although these names also denote the chemic… WebMar 16, 2024 · The copolymers of TMC and TrTMC were obtained by varying the feeding ratio of their monomers with good yields as hexane-isopropanol (9/1, v/v) insoluble part. The structures were confirmed by both FT-IR and 1 H NMR spectra, showing the copolymer composition was controlled in a good manner.
