Abstract
Six novel 1,2-bis(1-alkyl-2-methylindol-3-yl)cycloalkene derivatives w ere designed and synthesized by the intramolecular coupling reaction u sing low-valance titanium as catalyst. Photochromic properties of thes e compounds were initially investigated. The results show that the fat igue resistant properties of these compounds, the thermal stability an d the absorption maxima of their photocyclization products are influen ced by the ring size of cycloalkene and substituents on the heterocycl ic rings.
