The title compound, C16H12Cl2O, exhibits second-order nonlinear optical properties as it crystallizes in a non-centrosymmetric space group. The dihedral angle between the benzene rings is 34.02 (6)°. Intermolecular C—H...O interactions link the molecules to form chains along the c axis.

The synthesis of 5-arylazo- substituted bithiophenes and their UV-visible, solvatochromic and nonlinear optical properties (NLO) are described. In agreement with the solvatochromic data and also with the second-order molecular NLO characterization, the new donor-acceptor systems could find application as suitable solvatochromic probes and also as new NLO materials.

The electro-optical properties (nonlinear optical (NLO) and thermally activated delayed fluorescence (TADF) properties) of negative T-type dihydropyrene (DHP)-cyclophanediene (CPD) photoswitch were studied systematically in this work. An interesting “seesaw” phenomenon...
