Near-infrared Absorbing Polymethine Dyes Terminally Substituted by 1-Benzothiopyrylium Ring

Unsymmetrical polymethine near-infrared dyes terminally containing 1-benzothiopyrylium ring and N,N-dimethylamino group were first prepared from 2-methyl-, 4-methyl-, and 2,4-dimethyl-1-benzothiopyrylium salts.It is found that the maximum wavelength of these dyes on PMMA is remarkably shifted to a shorter wavelength (60-200 nm) compared with that in solution.

Synthesis of Heterocyclic Compounds : Part XXIV - Synthesis of 2,4-Disubstituted Thianaphthalenium Perchlorates and Thiachromans

Cyclodehydration of β-phenylmercaptopropyl phenyl ketone (V) and β-phenyl-β-phenylmercaptoethyl methyl ketone (VI) with 70percent perchloric acid gives a mixture of 2-methyl-4-phenylthianaphthalenium perchlorate (X), 4-methyl-2-phenylthianaphthalenium per
