Journal ArticleDOI
Two-Photon Excitation of Substituted Enediynes
John F. Kauffman,Joseph B. McGee Turner,Igor V. Alabugin,Boris Breiner,Serguei V. Kovalenko,Ekaterina Badaeva,Artëm E. Masunov,Sergei Tretiak +7 more
TL;DR: The theoretical computations confirmed that lowest energy TPA in benzannelated enediynes involves different orbitals than lowest energy one-photon absorbance and provided further support to the notion that introduction of donor and acceptor substituents at different ends of a molecule increases TPA.
Journal ArticleDOI
Frenkel-exciton Hamiltonian for dendrimeric nanostar
TL;DR: In this paper, a perylene chromophore attached to a poly-phenylacetylene dendrimer is obtained by computing the linear absorption of several segments using the collective electronic oscillator (CEO) approach.
Journal ArticleDOI
Excited-State Structure of Oligothiophene Dendrimers: Computational and Experimental Study
Ekaterina Badaeva,Michael R. Harpham,Ramakrishna Guda,Ozgun Suzer,Chang-Qi Ma,Peter Bäuerle,Theodore Goodson,Sergei Tretiak +7 more
TL;DR: The detailed information about the dendrimer 3D structure and excitations provides guidance for further optimizations of dendritic structures for nonlinear optical and opto-electronic applications.
Journal ArticleDOI
Formation of Assemblies Comprising Ru–Polypyridine Complexes and CdSe Nanocrystals Studied by ATR-FTIR Spectroscopy and DFT Modeling
Alexey Y. Koposov,Thomas Cardolaccia,Victor V. Albert,Ekaterina Badaeva,Svetlana Kilina,Thomas J. Meyer,Sergei Tretiak,Milan Sykora +7 more
TL;DR: ATR-FTIR studies reveal that when the solid film of NCs is exposed to an acetonitrile solution of 2, 3, or 4, the complexes chemically bind to the NC surface through their carboxylic acid groups, replacing TOPO ligands.
Journal ArticleDOI
Inter-aromatic distances in Geobacter sulfurreducens pili relevant to biofilm charge transport.
Hengjing Yan,Chern Chuang,Andriy Zhugayevych,Sergei Tretiak,Frederick W. Dahlquist,Guillermo C. Bazan +5 more
TL;DR: This paper presents a meta-analyses of the chiral stationary phase of the response of the immune system to polymethine-like substances and shows clear patterns in the response to polymers and organic solids.
