Efficient and rapid synthesis of oligo(p-phenylenevinylene) via iterative coherent approach

A general and controlled bidirectional growth strategy enables a very rapid and efficient construction of OPV compounds possessing functional groups such as aldehyde and mercapto groups at both ends. The strategy employs only one reaction type with high yields and stereoselectivities to grow the conjugated chains, eliminating the need for protecting groups in the overall intermediates.
