A novel diethynyl functionalized pillar[5]arene, that is a pentabenzenacyclodecaphane derivative, has been synthesized and polymerized with p-dihalobenzene to form a fishing rod-like conjugated polymer, where one of the benzenes in the pillar[5]arene rings is incorporated into a poly(arylene ethynylene) backbone.

Photovoltaic Behavior

A carbazole-based conjugated polymer bearing ruthenium complexes Pbpy(Ru)-Cz was synthesized aiming to obtain a material with dual functionalities of both light absorption and hole-transport for photovoltaic cells. Chemical structures of the monomers and polymers were confirmed by ¹H NMR, IR, and elemental analysis. Pbpy(Ru)-Cz showed good thermal stability and solubility. The absorption spectrum of Pbpy(Ru)-Cz showed a broader peak covering the wavelength range from 380 to 650 nm. Preliminary photovoltaic behavior was evaluated by fabricating photovoltaic cells. As measured under a 55 mW cm‾² compact white arc lamp, Voc, Jsc, FF and ηe of the device ITO/Pbpy(Ru)-Cz:PCBM/Al were 0.18 V, 0.019 mA cm‾², 0.22 and 1.40×10‾³%, pectively.

AbstractScanning-tunneling spectroscopy experiments have been performed on conjugated polymer films and have been compared to a three-dimensional numerical model for charge injection and transport. It is found that field enhancement near the tip apex leads to significant changes in the injected current, which can amount to more than an order of magnitude, and can even change the polarity of the dominant charge carrier. As a direct consequence, the single-particle band gap and band alignment of the organic material can be directly obtained from tip height-voltage (z-V) curves, provided that the tip has a sufficiently sharp apex.
