Novel ter(9,9-diarylfluorene)s were synthesized by a Suzuki-coupling reaction of 2-bromofluorene (1) and 2,7-fluorenediboronic ester derivatives (3) with high isolated yields (63-86%). The X-ray structure analysis ter(9,9'-spirobifluorene) (4aa) revealed that the conjugated chromophore adopts helical conformation. This conformation effectively releases steric interaction between fluorene moieties prevents inter-chromophore interactions. introduction aryl groups at C9 position was highly...

The external quantum efficiency of solar cells can be improved by using texturing pyramid- and honeycomb-like structures with minimum reflection. In this study, we investigated the reflection properties through rigorous coupled-wave analysis three-dimensional finite-difference time domains (FDTD) method to analyze close-packed structures. We also demonstrate a simple method-combining sub-wavelength-scale monolayer bilayer polystyrene spheres one-step reactive ion etching process-to fabricate...
