  • Drug-Assisted White Light Generation Via Self-Assembly
    Soumya Ranjan Panda, Kavyashree P., Dhananjaya Sahoo, Apurba Lal Koner
    Chemistry an Asian Journal, 2025
    White‐light (WL) generation using small organic molecules has gained significant attention from researchers working on the interface of supramolecular chemistry and organic materials. Self‐assembled multi‐chromophoric materials utilizing a drug molecule and microenvironment‐sensitive intramolecular charge transfer dye as an emitter offer the possibility of tunable emission. In this investigation, we focused on WL generation via the combination of a polarity‐sensitive red‐emitting styryl chromone (SC) and a blue‐emitting anticancer and psychotherapeutic drug Norharmane (NHM) in a self‐assembled micellar system. A detailed spectroscopic investigation allows us to understand the premicellar aggregation process of different types of surfactants with varying charges using the SC dye. Encapsulation of SC and NHM emitters inside the micellar system offers an improved fluorescent behavior, resulting in WL emission due to complementary wavelength overlap. The generated WL is highly photostable and thermally reversible in the self‐assembled system. This investigation highlights the significance of the co‐assembly of SC dye and NHM drug for the generation of a highly stable WL.
  • Linear and Kinked Oligo(phenyleneethynylene)s as Ideal Molecular Calibrants for Förster Resonance Energy Transfer
    Martin F. Czar, Frauke D. Breitgoff, Dhananjaya Sahoo, Muhammad Sajid, Navid Ramezanian, et al.
    Journal of Physical Chemistry Letters, 2019
    We show that oligo(phenyleneethynylene)s (oligoPEs) are ideal spacers for calibrating dye pairs used for Förster resonance energy transfer (FRET). Ensemble FRET measurements on linear and kinked diads with such spacers show the expected distance- and orientation-dependence of FRET. Measured FRET efficiencies match excellently with those predicted using a harmonic segmented chain model, which was validated by end-to-end distance distributions obtained from pulsed electron paramagnetic resonance measurements on spin-labeled oligoPEs with comparable label distances.

  • Efficient Microwave-Assisted Synthesis of Sonogashira-Coupled Perylene Monoimide Derivatives: Impact of Electron-Donating Groups on Optoelectronic Properties
    Vikas Sharma, Falguni Chandra, Dhananjaya Sahoo, Apurba L. Koner
    European Journal of Organic Chemistry, 2017
    An efficient microwave‐assisted Sonogashira‐coupling protocol for the synthesis of peri‐functionalized perylene monoimide dye derivatives was developed. This method was found to be significantly faster than the conventional coupling method and provided products with interesting optoelectronic properties in moderate to good yields. Electronic communication of the electron‐rich aryl and polyaryl groups with the perylene core through C≡C bonds was investigated.
  • Highly Fluorescent Peri-functionalized Perylenemonoimide Derivatives with Tunable Optical Properties for Selective Sensing of Electron-rich Aromatic Amines
    Vikas Sharma, Dhananjaya Sahoo, Falguni Chandra, Apurba L. Koner
    Chemistryselect, 2017
    A series of peri‐functionalized perylenemonoimide dyes containing an electron donating aromatic and polyaromatic group via Suzuki‐coupling reaction has been synthesized. Photophysical properties of the synthesized dyes are extensively investigated using various spectroscopic techniques. Introduction of substituent's at peri‐position shows a pronounced effect on emission properties. Electrochemical measurements suggest that the peri‐functionalization of perylenemonoimide dyes make reduction much more facile compared to unsubstituted dyes. Thereafter, an efficient and selective fluorescence quenching strategy via photo‐induced electron transfer process from electron‐rich aromatic amines to the synthesized dyes has been investigated.
  • Polar tagging in the synthesis of monodisperse oligo(p-phenyleneethynylene) s and an update on the synthesis of oligoPPEs
    Dhananjaya Sahoo, Susanne Thiele, Miriam Schulte, Navid Ramezanian, Adelheid Godt
    Beilstein Journal of Organic Chemistry, 2010
    One important access to monodisperse (functionalized) oligoPPEs is based on the orthogonality of the alkyne protecting groups triisopropylsilyl and hydroxymethyl (HOM) and on the polar tagging with the hydroxymethyl moiety for an easy chromatographic separation of the products. This paper provides an update of this synthetic route. For the deprotection of HOM protected alkynes, γ-MnO2 proved to be better than (highly) activated MnO2. The use of HOM as an alkyne protecting group is accompanied by carbometalation as a side reaction in the alkynyl–aryl coupling. The extent of carbometalation can be distinctly reduced through substitution of HOM for 1-hydroxyethyl. The strategy of polar tagging is extended by embedding ether linkages within the solubilising side chains. With building blocks such as 1,4-diiodo-2,5-bis(6-methoxyhexyl) less steps are needed to assemble oligoPPEs with functional end groups and the isolation of pure compounds becomes simple. For the preparation of 1,4-dialkyl-2,5-diiodobenzene a better procedure is presented together with the finding that 1,4-dialkyl-2,3-diiodobenzene, a constitutional isomer of 1,4-dialkyl-2,5-diiodobenzene, is one of the byproducts.
