In this study two chalcone diols namely DBHB, DBHE were synthesised by base catalysed Claisen-Schmidt condensation method comprising 1-3 diacetyl benzene and varying benzaldehyde. The UV-Visible spectroscopy, Fourier Transform Infrared spectroscopy was done to prove the formation of chalcone diols. Nuclear Magnetic Resonance spectroscopy was applied to confirm the structural orientation. The optical band gap energy of DBHB, DBHE were done by UV-Visible spectroscopy found to be 4.27 and 4.18 eV respectively. Thus the synthesised chalcone diols behave like a semiconductor material.
