The spectroscopic analysis of a newly synthesized 1,9-bis(2-cyano-2-ethoxycarbonylvinyl)-5-(2-chlorophenyl)-dipyrromethane (3) has been carried out using 1 H NMR, UV–Visible, FT-IR and Mass spectroscopic techniques. The presence of a 1 H NMR signal at 5.93ppm indicates that two pyrrole units joined together at meso position. The intense absorption in UV region at λ max (315nm)...
