Structure elucidation 4,4‴-Bis-(2-butyloctyloxy)-p-quaterphenyl in cyclohexane by the joint application of FTIR, Raman, UV and Visible spectroscopy

BBQ (4,4'''-Bis-(2-butyloctyloxy)-p-quaterphenyl) is one of the laser dyes, which appears as white, crystalline solid. A dye laser is a laser which uses an organic dye as the lasing medium, usually as a liquid solution. Some of the dyes are Rhodamine 6G, coumarin, stilbene, umbelliferone, tetracene and others. In this work, BBQ in cyclohexane is investigated in the room temperature spectroscopically. The used spectroscopic methods are Raman, FTIR and UV-Visible. The structure properties are identified with the spectroscopic methods. A dye can usually be used for a much wider range of wavelengths. The wide bandwidth makes them particularly suitable for tunable lasers and pulsed lasers. The solvent chosen cyclohexane is a cycloalkane.
