Efficient Synthesis and Characterization of Solvatochromic Fluorophore

A highly efficient designing and synthesis of an aryl‐substituted carbazole‐based fluorescent material (MeOCbzBP) has been carried out via tandem carbon–carbon (C–C)/carbon–nitrogen (C–N) bond formation by multiple Suzuki couplings and Cadogan cyclization followed by C–N cross‐couplings. Various organic solvents have been used to investigate photophysical, solvatofluorochromism, and photoluminescence characteristics of MeOCbzBP. The MeOCbzBP showed a reasonable redshifted absorption in UV region and photoluminescence enhancements in tetrahydrofuran/water mixtures. Furthermore, we also employed various theoretical functions to optimize the molecule both in the ground and excited states. A well‐known density functional theory was employed in a solvent phase with B3LYP/6‐31G(d) level of theories. We believe that the MeOCbzBP will provide a better platform to investigate the novel applications in the field of medicinal chemistry and chemical biology. A highly efficient designing and synthesis of an aryl‐substituted carbazole‐based material (MeOCbzBP) via tandem carbon–carbon (C–C)/carbon–nitrogen (C–N) bond formation by multiple Suzuki couplings and Cadogan cyclization followed by C–N cross‐coupling was carried out and investigated for solvatofluorochromism with its photophysical and photoluminescence characteristics in various organic solvents.
