✦ Synopsis


A new chromophore 6-methoxy-l-[2-(4-nitrophenyl)ethenyl]-azulene was synthesized and tested for the Second Harmonic Generation (SHG) in solid slate by the Kurtz powder technique. This compound was six times more efficient (58 times than the urea standard) than the unsubstituted compound 1-[2-(4-nitrophenyl)ethenyl]-azulene (10 times than the urea).
