The auxiliary methoxy aided triphenylamine donors derived coumarin chalcones and their OBO complexes with branched donor-pi-acceptor systems are synthesized and characterized. Their photophysical properties are extensively studied in solvents of different polarity. They show strong emission solvatochromism and have quantum yields up to 0.87. The BF2-complexation of coumarin chalcones enhanced the quantum efficiency by approximately 1.4 times compared to the uncomplexed chalcones. Frontier molecular orbital analysis and Generalised Mulliken Hush analysis revealed a strong intramolecular charge transfer character of these chromophores. The first, second and third order polarizability of these chromophores are evaluated by the solvatochromic method and supported by Density Functional Theory calculations using CAM-B3LYP/6-31g(d) method. The third order nonlinear optical susceptibilities of these chromophores obtained by Z-scan analysis showed very less values of the imaginary part. Replacement of N-ethyl donors by aryl amine groups provided branched push-pull systems with enhanced thermal stability and nonlinear optical response.

A new mitochondria-targeted fluorescent probe RBC, constructed using a coumarin moiety which was selected as the donor and a benzothiazole derivative as the acceptor, for SO2 derivatives (HSO3-/SO32-) was presented. The probe designed on a new FRET platform showed high selectivity and a low detection limit. Importantly, the probe could respond to HSO3-/SO32- within 35 s. Furthermore, the probe could target mitochondria and was successfully used for fluorescence imaging of endogenous bisulfite in HepG2 with low cytotoxicity, which significantly assisted in cancer diagnosis.
