Tuning mesomorphic, spectral and nonlinear optical behavior in chalcogenophene triads: the role of oxygen, sulfur, and selenium

Key Points

• The study aims to explore how the identity of heteroatoms like oxygen, sulfur, and selenium influences the optical properties of chalcogenophene compounds.
• Synthesis of nine new chalcogenophene-based compounds
• Characterization of their mesomorphic and spectral behavior
• Assessment of nonlinear optical properties
• Different heteroatoms significantly affect the nonlinear optical behavior
• Spectral properties vary with the type of heteroatom present
• Compounds exhibited distinct mesomorphic behaviors based on their molecular structure
