Fluorescent molecular platforms are highly sought after for their applications in biology and optoelectronics but face challenges with solid-state emission quenching. To address this, bulky substituents or aggregation-induced luminogens to restrict intramolecular motion used enhance the brightness. Here, we have successfully engineered a novel class of boron complexed pyrrolide salicyl-hydrazone fluorophores named BPSHY. These dyes were synthesized through diversity-oriented condensation pyrrole salicylaldehyde derivatives combined various aromatic boronic acids. The resulting 3D structures, owing axially substituted aryl groups, impart excellent solubility variety solvents. Significantly, BPSHY exhibit strong absorption visible region remarkably large Stokes shifts. Crucially, they demonstrate intense aqueous solutions due effects.

Tetracoordinate boron-based fluorescent materials have shown extensively applications in chemistry, biology and science owing to their unique optoelectronic properties. However, constructing chiral boron-stereogenic fluorophores through practical universal strategies remains rare challenging. Herein, as a proof of concept, we report an enantioselective postfunctionalization boron dipyrromethene dyes (BODIPYs), acess BODIPYs moderate good yields with commendable enantioselectivity. Chiral attracted increasing attention not only distinctively photophysical properties circularly polarized luminescence (CPL) materials, but also diversely structural modification.

We present a new, straightforward, and versatile approach that utilizes regioselective brominated precursors to synthesize both asymmetric symmetric S-zig-zag-fused BODIPYs (s-TFB bis-TFB) in moderate yields (45% 40%, respectively). X-ray structure analyses reveal the planar rigidity of BODIPY skeleton is progressively enhanced with an increasing number thiopyran rings. The annulation S-heteroaromatic rings at zig-zag edge core results blue-shifted absorption emission spectra, bis-TFB exhibiting maxima 530 539 nm elevated LUMO energy levels. In contrast, oxidation s-TFB m-CPBA demonstrates significant site selectivity, affording four products, namely s-s-SFB, s-bis-SFB, bis-s-SFB, bis-bis-SFB, ranging from 22% 36%. These oxidated derivatives display large red-shifted spectra (e.g., 648 735 for s-bis-SFB), along more stable HOMO levels reduced HOMO-LUMO gaps. This cyclization/oxidation strategy enables precise tuning optoelectronic properties, opening new avenues dye design application.
