Synthesis and charge transport studies of stable, soluble hexacenes

Creator:: Purushothaman, Balaji, Parkin, Sean R., Kendrick, Mark J., David, Daniel, Ward, Jeremy W., Yu, Liyang, Stingelin, Natalie, Jurchescu, Oana D., Ostroverkhova, Oksana, and Anthony, John E.
Abstract:: Acenes larger than pentacene are predicted to possess enticing electronic properties, but are insoluble and prone to rapid decomposition. Utilizing a combination of functionalization strategies, we present stable, solution processable hexacenes and an evaluation of their hole and electron transport properties.

Temperature dependence of exciton and charge carrier dynamics in organic thin films

Creator:: Platt, A. D., Kendrick, M. J., Loth, M., Anthony, J. E., and Ostroverkhova, O.
Abstract:: We report on physical mechanisms behind the temperature-dependent optical absorption, photoluminescence (PL), and photoconductivity in spin-coated films of a functionalized anthradithiophene (ADT) derivative, ADT-triethylsilylethynyl (TES)-F, and its composites with C₆₀ and another ADT derivative, ADT-TIPS-CN. Measurements of absorption and PL spectra, PL lifetimes, and transient photocurrent were performed at temperatures...

Enhanced charge photogeneration promoted by crystallinity in small-molecule donor-acceptor bulk heterojunctions

Creator:: Paudel, Keshab, Johnson, Brian, Thieme, Mattson, Haley, Michael M., Payne, Marcia M., Anthony, John E., and Ostroverkhova, Oksana
Abstract:: We examined sub-nanosecond time-scale charge carrier dynamics in crystalline films of a functionalized anthradithiophene (ADT) donor (D) with three different acceptor (A) molecules. A four-fold enhancement in ultrafast charge carrier separation efficiency was observed in D/A blends with a fullerene acceptor added at 7–10 wt. % concentrations, whereas a gradual...

Organic semiconductor composites: influence of additives on the transient photocurrent

Creator:: Day, Jonathan, Platt, Andrew D., Ostroverkhova, Oksana, Subramanian, Sankar, and Anthony, John E.
Abstract:: We report on the effect of various guest molecules added to a functionalized anthradithiophene (ADT) host on photoexcited charge carrier dynamics in solution-deposited thin films, from ~100 ps to >100 μs after photoexcitation with 100 fs laser pulses. An addition of 2 and 5 wt % of C60 to a...

Charge carrier dynamics in organic semiconductors and their donor-acceptor composites: Numerical modeling of time-resolved photocurrent

Creator:: Johnson, Brian, Kendrick, Mark J., and Ostroverkhova, Oksana
Abstract:: We present a model that describes nanosecond (ns) time-scale photocurrent dynamics in functionalized anthradithiophene (ADT) films and ADT-based donor-acceptor (D/A) composites. By fitting numerically simulated photocurrents to experimental data, we quantify contributions of multiple pathways of charge carrier photogeneration to the photocurrent, as well as extract parameters that characterize charge...

Design of organic ternary blends and small-molecule bulk heterojunctions: photophysical considerations

Creator:: Rajesh, Kallarakkal Ramakrishnan, Paudel, Keshab, Johnson, Brian, Hallani, Rawad, Anthony, John, and Ostroverkhova, Oksana
Abstract:: We explored relationships between photophysical processes and solar cell characteristics in solution-processable bulk heterojunctions (BHJs), in particular: (1) polymer donor:fullerene acceptor:small-molecule (SM) nonfullerene acceptor, (2) polymer donor:SM donor:SM nonfullerene acceptor, and (3) SM donor:SM nonfullerene or fullerene acceptor. Addition of a nonfullerene SM acceptor to “efficient” polymer:fullerene BHJs led to...

Physical and biochemical changes in pears during storage and ripening

Creator:: Date, Waman Bhaskar
Abstract:: A study has been made of the interrelations between certain of the physical and biochemical changes in three varieties of pears during storage and ripening. The metabolic changes which occurred in the fruit during cold temperature storage were found to influence with development of certain characteristics associated with dessert quality...
