Synthesis, growth and characterization of π conjugated organic nonlinear optical chalcone derivative

► A novel thiophene substituted NLO crystal has been grown using methanol as solvent. ► The crystals were characterized by using FTIR, TGA/DTA and UV-visible spectroscopy. ► The n2 and χ(3) values is of the order of 10−11 cm2 W−1 and 10−13 esu respectively. ► The crystals show better optical limiting behavior.
