Recently incorporation of Lewis acidic boron centers into π systems has received a lot of attention due to the intriguing photophysical properties exhibited by such systems. Many of these compounds find widespread applications in linear and non-linear optics, as electron conduction layers in OLED's and also as sensor materials for nucleophiles. We have developed a methodology for introduction of Lewis acidic boron moieties into the side-chain of polymers with polystyrene as the backbone. The Lewis acidity of the boron centers as well as the photophysical properties have been fine tuned by integrating various chromophoric aryl groups onto the boron centers. More interestingly these polymeric Lewis acids have been found to readily bind Lewis bases like pyridine and fluoride. We have systematically studied the changes brought about in the absorption and emission characteristics due to the Lewis acid-base type interactions.
