Abstract

Abstract The photophysics of three thiacarbocyanine dyes, 3, 3'-dimethylthiacarbocyanine iodide (DMTCC), 3, 3'-diethylthiacarbocyanine iodide (DETCC), and 3, 3′- dipropylthiacarbocyanine iodide (DPTCC) was studied when adsorbed on microcrystalline cellulose in the concentration range from 5.0· 10-4 to 10.0 μmol g-1. Using ground-state diffuse reflectance absorption technique, only H aggregate formation was detected for all ...
