The thesis contains five chapters. The first chapter describes the synthesis of chiral mainchain polymers bonded with (R,R)-salen and 1,4-dioctyloxybenzene as alternate segments. The chapter two deals with the titanium polymer complex formation and its application for 1,2-addition of trimethylsilyl cyanide (TMSCN) to aldehydes. The third chapter focuses on chiral titanium-catalyzed asymmetric sulfoxidation with aqueous hydrogen peroxide. The fourth and fifth chapters deal with the use of the polymers as chemosensor for cascade Zn2+ detection and chiral recognition toward optically active 2-substituted pyridines.
