Absorption spectrum of monomeric pseudoisocyanine: A new perspective and its implications for formation and spectral response of J-aggregates in solution and in thin films
Gülen, Demet; Özçelik, Serdar (Elsevier, 2008-05)We argued against the current spectral assignment for absorption spectrum of monomeric PIC which is widely accepted since the pioneering works of Scheibe and Jelley [G. Scheibe, Angew. Chem. 49 (1936) 563; E.E. Jelly, ... -
Controlled Formation of the Two-Dimensional TTBC J-Aggregates in an Aqueous Solution
Birkan, Burak; Gülen, Demet; Özçelik, Serdar (American Chemical Society, 2013-09-30)Strong experimental and theoretical evidence was provided on the controlled formation of the two-dimensional J-aggregates that were assembled in the herringbone morphology. The exciton-band structure formation of ... -
Investigation of structure-spectroscopy-function relationship of twodimensional J-aggregates of tetrachlorobenzimidazolorcarbocyanine preferentially oriented in poly-vinly-alcohol thin films
Gülen, Demet; Atasoylu, Onur; Özçelik, Serdar (Elsevier, 2009-01)The structure–spectroscopy–function relationship of 1,1 0 ,3,3 0 -tetraethyl-5,5 0 ,6,6 0 -tetrachlorobenzimidazolocarbocyanine (TTBC) aggregates is studied using a combination of experimental and theoretical ... -
Polarized absorption spectra of highly oriented two-dimensional aggregates of tetrachlorobenzimidazolocarbocyanine in thin films
Özçelik, Serdar; Gülen, Demet (Elsevier, 2008-05)Reaching a control on the mesoscopic morphology and internal molecular arrangement of cyanine aggregates is an important step for realization of devices with tailor-made optical properties. Despite a wealth of research, ...
