A homologous series of bis-diphenylphosphine oxides (C 6 H 5 ) 2 PO-(CH 2 ) n PO(C 6 H 5 ) 2 (with n 2 ± 8; denoted 2 ± 8] have been investigated to explore the effects of a range of competing and cooperative intermolecular and intramolecular interactions on the structural properties in the solid st
## Abstract A series of protected L‐norvaline homo‐oligomers from dimer to heptamer was prepared by the dicyclohexylcarbodiimide and acid azide coupling methods. In the course of our synthetic approach t‐butyloxycarbonyl as the N‐protecting and methyl ester as the C‐protecting end groups were used.
Electronic-structure calculations based upon the Pariser᎐Parr᎐Pople semiempirical Hamiltonian were applied to short-chain oligomers of the conducting Ž . Ž . polymer poly p-phenylenevinylene PPV to study the effects of appending methoxy groups along the backbone as well as push᎐pull nitro and amino
