Abstract

Some C2v symmetric cyclopenta [2, 1-b; 3, 4-b′] bithiophenes differently substituted at the 4 position with a calix [4] arene group were synthesized and electrochemically polymerized by anodic coupling. The polymers were characterized by cyclic voltammetry, UV-vis and FTIR spectroscopy. Quartz crystal microbalance analysis showed strong affinity and selectivity of the polymers for toluene and acetone from the gas phase. The absorption ...
