Water mediated organicsynthesis is a fascinating approach in chemistry. We have attempted catalyst free synthesis of thermally stable near infra-red (NIR) emitting quinone fused coumarins with a benzothiazole/benzimidazole acceptor in aqueous medium. The synthesis was attempted using naturally occurring 2-hydroxy-1,4-naphthoquinone (Lawsone). It is an efficient and environmentallyfriendly approach
