Rh (I) and Pd (II) catalysts were used to prepare humidity sensitive organometallic polymers pre- pared from N , N -dimethylproparylamine (DMPA) or the corresponding chlorohydrate (DMPA • HCl) as monomers. Pristine and iodine doped polymers were characterized and their sensing properties were investigated and here discussed. The responses to relative humidity and short alcohols variations of sen- sors based on these polymeric membranes were investigated. An interesting response towards methanol and ethanol was found. Long term stability, fast response time and resistance to high humidity atmo- sphere, were achieved.
The growing interest and activity in the field of sensor technologies requires a forum for rapid dissemination of important results: Sensor Letters is that forum. Sensor Letters offers scientists, engineers and medical experts timely, peer-reviewed research on sensor science and technology of the highest quality. Sensor Letters publish original rapid communications, full papers and timely state-of-the-art reviews encompassing the fundamental and applied research on sensor science and technology in all fields of science, engineering, and medicine. Highest priority will be given to short communications reporting important new scientific and technological findings.
