Single-mode fiber connectors are demonstrated with 125 µm diameter thin-coated fibers directly inserted into connector ferrules. Low insertion loss of less than 0.3 dB is achieved due to the high concentricity of the coating.

It is challenging to realize both a fully conjugated rigid polymer backbone and high molecular weight at the same time. Previously, we reported a DPP-FT4 polymer with molecular weight up to 30 kDa. A new design and synthesis was required to overcome

Thin coated single-mode fibers with coating diameters from 125 to 175 μm are fabricated and characterized. The fibers show excellent coating concentricity and attenuation similar to 250 μm coated fiber on shipping reels.

Radical cations of a heptathienoacene α,β-substituted with four n-decyl side groups (D4T7(.) (+) ) form exceptionally stable π-dimer dications already at ambient temperature (Chem. Comm. 2011, 47, 12622). This extraordinary π-dimerization process
