Abstract
A new chromophore 6-methoxy-1-[2-(4-nitrophenyl)ethenyl]-azulene was s ynthesized and tested for the Second Harmonic Generation (SHG) in soli d state by the Kurtz powder technique. This compound was sis times mor e efficient (58 times than the urea standard) than the unsubstituted c ompound 1-[2-(4-nitrophenyl)ethenyl]-azulene (10 times than the urea).
