Realistically designed bis(indolyl)methanes from beta-chloro-alpha,beta-unsaturated aldehydes exhibited remarkable naked eye sensitivity towards Cu2+ ion. A green one pot technique has been developed for their synthesis using PMA-Cellulose as a reusable solid acid support/catalyst under solvent free condition. The procedure offered excellent yields within a short period of time.
