Determination and varying of of the optoelectronic parameters of 1, 4-Bis [2-(3-N-ethylcarbazoryl)-vinyl] benzene organic light emitting material (OLEM) with solvents

Abstract

Effects of solvents on optical properties of solutions of 1, 4-Bis [2-(3-N-ethylcarbazoryl)-vinyl] benzene (BCzVB) organic light emitting material (OLEM) have been studied by using solution method. The maximum mass extinction coefficient values of solutions of BCzVB material for DCM, THF, and chloroform solvents were determined to be 61.603, 51.295 and 22.647 Lg-1cm-1, respectively. The loss factor value for chloroform is the highest value, while the loss factor value for DCM solvent is the lowest value. The optical conductance values of the BCzVB are higher than the electrical conductance values of the BCzVB. It was found that the optical band gap value of the BCzVB material have increased by changing for various solvents. DCM, THF, and chloroform solvents were used to reach lower Eg values (2.815, 2.835 and 2.851, respectively).
