Journal ArticleDOI
A Highly Selective Chemosensor for Cyanide Derived from a Formyl-Functionalized Phosphorescent Iridium(III) Complex
K. S. Bejoymohandas,K. S. Bejoymohandas,Ajay Kumar,S. Sreenadh,E. Varathan,Sunil Varughese,V. Subramanian,M. L. P. Reddy,M. L. P. Reddy +8 more
TL;DR: In this work, phosphorescent test strips have been constructed by impregnating Whatman filter paper with IrC for the trace detection of CN(-) in the contact mode, exhibiting a detection limit at the nanogram level (∼265 ng/mL).
Journal ArticleDOI
White light emitting single polymer from aggregation enhanced emission: a strategy through supramolecular assembly
Ezhakudiyan Ravindran,S. Ananthakrishnan,E. Varathan,E. Varathan,Venkatesan Subramanian,Venkatesan Subramanian,N. Somanathan,N. Somanathan +7 more
TL;DR: In this paper, an efficient pure white electroluminescent polymers, obtained by copolymerization of 9,9-dihexylfluorene as a blue host with (E)-2,7-dibromo-9H-fluoren-9-yl-2-cyano-3-(4-(dimethylamino)phenyl) acrylate (FCP) as a yellow emitting covalent dopant with AIEE properties on the main chain of the copolymers, have been designed and synthesized.
Journal ArticleDOI
A solution processable fluorene-fluorenone oligomer with aggregation induced emission enhancement.
S. Ananthakrishnan,E. Varathan,Ezhakudiyan Ravindran,N. Somanathan,Venkatesan Subramanian,Asit Baran Mandal,Janardanan D. Sudha,Janardanan D. Sudha,Rajaraman Ramakrishnan,Rajaraman Ramakrishnan +9 more
TL;DR: A novel solution processable fluorenone based small molecule with an Aggregation Induced Emission Enhancement (AIEE) property and the presence of the fluore None moiety in FF triggers the AIEE property.
Journal ArticleDOI
Photophysical and electroluminescence properties of bis(2′,6′-difluoro-2,3′-bipyridinato-N,C4′)iridium(picolinate) complexes: effect of electron-withdrawing and electron-donating group substituents at the 4′ position of the pyridyl moiety of the cyclometalated ligand
K. S. Bejoymohandas,K. S. Bejoymohandas,Arunandan Kumar,Sunil Varughese,E. Varathan,V. Subramanian,M. L. P. Reddy,M. L. P. Reddy +7 more
TL;DR: In this article, a series of 2′,6′-difluoro-2,3′-bipyridine cyclometalating ligands were synthesized by substituting electron-withdrawing (CHO, CF3, and CN) and electron-donating (OMe and NMe2) groups at the 4′ position of the pyridyl moiety and utilized them for the construction of five new iridium(III) complexes.
Journal ArticleDOI
Rational Design of Carbazole- and Carboline-Based Ambipolar Host Materials for Blue Electrophosphorescence: A Density Functional Theory Study
TL;DR: In this article, the influence of the number (mono-, di-, and trisubstituted) and positions of Cb1 and Cbz substitution on an array of electronic properties of the designed hosts was investigated.
