An efficient neat mechanochemical method for the synthesis of fluorescent indolylquinonlines via A3‐coupling reaction of 1‐phenylsulfonylindole‐3‐carbaldehyde (1), substituted anilines 2(a–j) and substituted phenylacetylene 3(a,b) using SiO2 as an effective catalyst has been developed. The photophysical properties of newly synthesized indolylquinoline derivatives 4(a–l) were established and it depends on the nature of substituent at C6 position of quinoline moiety.
