Exploring the Optical and Redox Properties of π-Conjugated Boron Difluoride Formazanate Dyes
… synthesis and characterization of a series of oligoynes with up to 10 alkyne units using BF2 formazanates as end-caps. Not only did BF2 formazanates stabilize the oligoynes, but they also introduced unique optical and redox properties. The resulting compounds exhibited a blend of properties …

Quantum Monte Carlo study of low dimensional materials
… electronic properties of 1D hydrogen-terminated oligoynes and polyyne are studied by calculating their DMC quasiparticle and excitonic gaps. By minimising the DMC energy of free-standing polyyne with respect to the lattice constant and the bond-length alternation, DMC predicts geometry in …

Electronic properties of nano and molecular quantum devices
… molecular length within a homologous series of oligoynes, Me3Si― (C≡C)n―SiMe3 (n = 2, 3, 4, or 5), is shown to depend strongly on the solvent medium. Single molecule junction conductance measurements have been made with the I(s) method for each member of the series Me3Si―(C≡C)n―SiMe3 (n = 2, 3, …
