Photochemistry of photochromic 2-indolylfulgides with substituents at the 1 '-position of the indolylmethylene moiety Academic Article uri icon

abstract

  • Substituted 2-indolyl fulgides with methyl and isopropyl groups at the 1-position of the indolylmethylene moiety were synthesized. Steric effects on the spectroscopic and photochromic properties were measured and discussed. The methyl and isopropyl groups at the 1-position decrease the quantum efficiency of the E-Z isomerization, while increase the coloration quantum yield. The thermal stability and fatigue resistance of these fulgides were determined.
