abstract = "A novel vapochromic complex has been used to develop an optical fiber device sensitive to pyridine vapors. In solid state, this material is blue, and in the presence of pyridine vapors, its color changes to pink-white. The vapochromic material is solved in tetrahydrofuran (THF) and immobilized in a plasticized polymeric, fixing it onto a cleaved ended optical fiber pigtail by dip coating. The fabrication process was optimized in terms of number of dips and dipping speed, evaluating the final devices by dynamic range. Employing a reflection set up, the response of the sensors was registered in terms of absorbance spectrum and changes in reflected optical power. Devices showing a linear response with different vapors concentrations were obtained, with a detection limit of 1 PPM (v/v).",
