Abstract A novel conjugated alkylfluorene decorated phenothiazine carbaldehyde, 10-(9,9-diethyl-9 H -fluoren-2-yl)-10 H -phenothiazine-3-carbaldehyde ( FPTZC ) was synthesized and fully characterized by spectroscopic, elemental and single crystal XRD analyses. The geometry and electronic structures were arrived using B3LYP/6-31G++(d,p) calculations. The geometrical parameters, resulted from single

The requisition of small light emitting organic molecules is on the rise in the field of organic electronics. This study is aimed at synthesis of fluorene based chromophores which possess promising optoelectronic properties. The characterization of synthesized derivatives was carried out by spectroscopy (H-1-NMR and C-13-NMR) and spectrometry (EI-MS). The optical properties evaluated by using UV-Vis spectroscopy, were from 394 to 420 nm, Fluorescence ranged 48 nm-113 nm, HOMO energy levels are -6.75 eV to -7.15 eV WMO -4.08 to -4.52eV with a band gap energy values 2.63-2.67 eV. The band gap energy values suggest that these synthesized molecules can be manipulated in the designing of blue and green OLEDS. (C) 2017 Elsevier Ltd. All rights reserved.
