A rapid, ultrasound assisted base-catalysed metal free synthesis of a novel series linear prenylarenes 17 incorporated with donor-acceptor functionalities is described via carbanion-induced ring transformation of 4-amino-6-aryl-3-cyano-2H-pyran-2-ones 15 with 6-methylhept-5-en-2-one 16 at room temperature with high yields. Notably, all of the synthesised prenylarenes exhibited blue fluorescence in the 406–468 nm region. The stokes shift, optical band gap, and quantum yield of compounds 17a-17l were computed using their absorption and emission spectra. A significant positive solvatochromic effect was observed, and concentration studies revealed the non-aggregating behaviour of synthesised prenylarenes. Single crystal X-ray diffraction analysis of 17d revealed that crystal belongs to triclinic system with P-1 space group with twisted phenyl rings.
