The solution properties of a novel soluble polydiacetylene, poly[1,6-bis(3,6-dihexadecyl-N-carbazolyl)-2,4-hexadiyne] (polyDCHD-HS), have been investigated by use of spectroscopic (UV-VIS absorption, fluorescence and FT-Raman) and light scattering techniques in benzene and toluene, The unique spectroscopic and molecular properties of these...

Solutions of polycarbazolyldiacetylene in benzene were studied using ultrabroadband sub-10-fs excitation pulses obtained from a visible optical parametric amplifier. The semiconducting polymers exhibited a steep onset of ground state absorption. The differential transmission signal was observed to be dependent on pump-probe delay at the probe...

A series of fulleropyrrolidines-conjugated bridge-ferrocene or triazene oligomers were selectively synthesized by the Sonogashira reaction by applying the step-by-step approach. The bridge is constituted by 1, 2 and 3 benzoateethynylene units (BzE) and bears triazene (Et2N3) or ferrocene as terminal groups affording the C60-2PEN3and...
