For thermoelectric and other device applications there has been great interest in the chemical doping of conjugated polymer films. Solution followed by film deposition generally produces poor-quality films, but this issue can be alleviated sequential doping: a pure is deposited first, dopant then added as second processing step, preserving quality structure original film. In paper, we compare two methods for films: evaporation doping, where controlled thickness via thermal sublimation to...
Social distancing during the COVID-19 pandemic presents mental health and academic obstacles for students. As can strongly influence performance, addressing loss of community by transitioning to distance education, midsemester, is imperative. This work draws upon wellness benefits associated with online gaming applies it ChemDraw. The goal improve class' social while teaching valuable organic chemistry skills. In this paper, a molecule, speed-drawing tournament (Molecule Madness) presented...
A novel methoxylated 1,4-bisbenzyl fullerene adduct gives better performance in polymer:fullerene bulk heterojunction photovoltaic devices than traditional PCBM, and it is easily synthesized.
Bulk heterojunction (BHJ) photovoltaics based on blends of conjugated polymers and fullerenes require an optimized nanoscale morphology. Casting BHJ films using solvent additives such as 1,8-diiodooctane (DIO), 1,8-octanedithiol (ODT), chloronapthalene (CN), or diphenyl ether (DPE) often helps achieve this proper morphology: adding just a few volume percent additive to the casting solution can improve polymer/fullerene mixing phase separation, so that have become staples in producing...
The polymer chain orientation and degree of crystallinity within a polymer:fullerene bulk heterojunction (BHJ) photovoltaic can greatly impact device performance. In general, face-on is preferred for charge conduction through sandwich-structure devices, but many conjugated polymers, an edge-on conformation energetically favored. this work, we examine the effects different processing techniques on photovoltaics based...
Bay-linked diperylenediimide (di-PDI) molecules are finding increasing use in organic electronics because of their steric hindrance that "twists" the two monomer units relative to one another, decreasing molecular aggregation. In this paper, we explore electronic spectroscopy and ultrafast dynamics singly linked β-β-S-di-PDI (2,9′-di(undecan-5-yl)-2′,9-di(undecan-6-yl)-[5,5′-bianthra[2,1,9-def:6,5,10-d′e′f′]diisoquinolin]-1,1′,3,3′,8,8′,10,10′(2H,2′H,9H,9′H)-octaone).

Abstract Denaturation of oxidized cytochrome c (cyt c) adsorbed to a hydrophilic fused silica surface was studied by UV‐VIS attenuated total reflection (ATR) spectroscopy using multiple optical pass system newly developed this lab. Cyt adsorption at neutral pH gave an equilibrium constant K = 2 × 10 5 M −1 and coverage 63% monolayer saturation. Protein unfolding acid denaturation equilibrating bound cyt with buffers ranging in from 2. orientation were calculated based on theoretical model...
