Luminescent Co-Assemblies of Donor-Acceptor Dimeric Cyanostilbenes with (Bio)Anionic Polymeric Templates
Supratim Banerjee, Susmit Som, Sharanabasava D. Hiremath, and Richeek Sarkar
Wiley
AbstractAmphiphilic dimeric cyanostilbenes with two donor‐acceptor moieties connected through variable aliphatic linkers displayed aggregation in aqueous media to produce red emissive nano‐assemblies. In the presence of anionic biopolymers such as ctDNA and heparin, they formed electrostatically driven co‐assemblies with enhanced luminescence. Moreover, due to the chiral nature of the bio‐templates DNA and heparin, the co‐assemblies demonstrated induced chirality features. Although the central double bond in cyanostilbenes is known to undergo various photochemical conversions, these dimeric donor‐acceptor cyanostilbenes, in their self‐assembled state, essentially remained photoinactive under UV irradiation. However, in the bio‐templated co‐assemblies, they showed comparatively higher photo‐reactivity, which was especially prominent for the ctDNA based co‐assemblies. We also found that these co‐assemblies can be used as artificial light‐harvesting systems by incorporating acceptor dyes and this led to the generation of amplified emission from the acceptor dyes in the NIR range of the spectrum. Furthermore, the co‐assemblies demonstrated selective fluorescence quenching in the presence of metal ions such as Cu2+ and Fe2+, highlighting their potential for metal‐ion sensing applications.

Metal Ion Responsive Luminescent Bio-Templated Co-Assemblies: Label-Free Detection of Multi-Metal Ions in Aqueous Media
Sharanabasava D. Hiremath, Nitish Kumar, and Supratim Banerjee
Wiley
AbstractRecently, anionic bio‐templates have emerged as promising platforms for designing dynamic and stimuli‐responsive chromophoric assemblies capable of light harvesting in aqueous media thereby mimicking natural photosynthesis. Here, we present multi‐metal ion‐responsive luminescent co‐assemblies between cationic pyrene‐imidazolium amphiphile and anionic bio‐templates (ATP, heparin, and DNA) in aqueous media. The anionic bio‐templates enhance Förster resonance energy transfer (FRET) in the co‐assemblies, with pyrene serving as an excellent donor for generating tunable multi‐luminescent materials with embedded acceptor dyes. However, a significant loss in energy transfer towards acceptor dyes was observed in the presence of various metal ions, attributed to excimeric emission quenching facilitated by electron transfer between the pyrene chromophore and metal ions. Interestingly, detailed studies revealed that only ATP‐based co‐assemblies exhibited quenching phenomena in the presence of metal ions, contrasting with heparin and ctDNA co‐assemblies. Additionally, label‐free detection of multi‐metal ions in aqueous environments, such as Fe2+, Fe3+, and Cu2+ ions, was successfully achieved with lower detection limits of 0.01 μM (3 ppb), 0.12 μM (30 ppb), and 0.58 μM (150 ppb) respectively. These co‐assemblies hold significant promise for practical applications in environmental and biomedical sensing, enabling sensitive monitoring of metal ion concentrations.

A New Series of D<inf>1</inf>-A-D<inf>2</inf>-type ESIPT-TICT-AIE Active Orange-to-red Emissive Unsymmetrical Azines: Their All-throughout Mechanochemical Synthesis and Exploration of Photophysical Properties

Wiley
AbstractAzines are interesting compounds exhibiting aggregation‐induced‐emission (AIE) and twisted‐intramolecular‐charge‐transfer (TICT) properties that have exciting prospects in chemosensing and bioimaging applications. They commonly have symmetrical structures and there is no report on red‐emissive unsymmetrical azines. Herein, we report a novel class of orange‐to‐red emissive hydroxybenzothiazole(HBT)‐based unsymmetrical azines (BTDPA) with triple photophysical characteristics of ESIPT‐TICT‐AIE. The dyes were synthesized by an all‐throughout mechanochemical route in a sustainable way. They displayed D1‐A‐D2 character and fluoresce strongly both in organic solvents due to ESIPT and in the solid state by AIE via TICT. The incorporation of different electron‐withdrawing groups (EWGs) and electron‐donating groups (EDGs) at either HBT or diphenyl‐methylene moiety resulted in tunable fluorescence properties. The red‐emissive character was achieved by keeping EDG both at HBT (−OMe) and the diphenyl‐methylene moiety (−NMe2) (λem 680 nm). The dyes exhibited good quantum yields, large Stoke shifts (upto 293 nm) and were utilized in nitroaromatics and Cu2+ sensing.
