Although Staudinger realized makromoleküles had enormous potential, he likely did not anticipate the consequences of their universal adoption. With 6.3 billion metric tons plastic waste now contaminating our land, water, and air, we are facing an environmental public health crisis. Synthetic polymer chemists can help create a more sustainable future, but on right path to do so? Herein, comprehensive literature survey reveals that there has been increased focus "sustainable polymers" in...
Abstract [2.2]paracyclophane (pCp), unlike many π‐building blocks, has been virtually unexplored in supramolecular constructs. Reported here is the synthesis and characterization of first pCp derivatives capable programmed self‐assembly into extended cofacial π‐stacks solution solid state. The design employs transannular (intramolecular) hydrogen bonds (H‐bonds), hitherto unstudied pCps, between pseudo‐ ortho ‐positioned amides a pCp‐4,7,12,15‐tetracarboxamide (pCpTA) to preorganize...
A two-week summer camp for high school students focused on sustainable polymers was developed and implemented. Students took part in experiments interactive lessons that demonstrate polymer chemistry fundamentals alongside associated sustainability challenges opportunities. For example, concepts related to chemical properties (reactivity, structural architecture, molecular weight) physical (density, tensile strength, thermal properties) were discussed, as well how these affect materials'...

Reported here is the first synthesis, X-ray crystal structure, and derivatization of benzotrifuran (BTFuran). Single analysis BTFuran shows a tight hexagonal packing stabilized by π-stacking interactions C-H···O contacts. α-Lithiation enables preparation reactive intermediates suitable for cross-coupling reactions, allowing access to representative BTFuran-containing π-conjugated systems.
Device-relevant π-conjugated oligothiophenes with the canonical nucleobases directly embedded into π-framework have been designed, synthesized, and characterized. These oligomers offer ability to tune optoelectronic properties via intimate merging of nucleobase molecular electronic structure base-pairing fidelity. Analysis their optical in a hydrogen-bond-disrupting solvent (DMF) indicates that identity influences intrinsic semiconductors. differences are supported by DFT calculations which...
Reported here is the synthesis, characterization, and isodesmic supramolecular polymerization of [3.3]paracyclophane-5,8,14,17-tetracarboxamide ([3.3]pCpTA). The self-assembling monomer, a bridge-expanded homolog [2.2]paracyclophane-4,7,12,15-tetracarboxamide ([2.2]pCpTA), forms homochiral assemblies in nonpolar solution solid state through double-helical intermolecular transannular hydrogen bonding. additional methylene unit [3.3]paracyclophane bridge results weakened assembly for...
A series of simple ditopic hydrogen-bonding-capable molecules functionalized with 2,4-diamino-1,3,5-triazine (DAT), barbiturate (B), and phthalhydrazide (PH) on both termini a 2,2′-bithiophene linker were designed synthesized. The intrinsic electronic structures the DAT, PH, B investigated ground-state density functional theory calculations. Their solution absorbance was UV-vis, where it found that increasing size R group substituents bithiophene resulted in general blue-shift maximum....
Abstract A series of [2.2]paracyclophane‐bisamide regioisomers and alkylated comparators were designed, synthesized, characterized in order to better understand the transannular hydrogen bonding [2.2]paracyclophane‐based molecular recognition units. X‐Ray crystallography shows that is maintained solid‐state, but no stereospecific self‐recognition observed. The assignment both transannularly intermolecularly bonded N−H stretches could be made by infrared spectroscopy, effect on amide bond...
Organic photovoltaics are again gaining traction as device power conversion efficiencies have increased substantially over the last two years. Despite these improved efficiencies, long-term stability remains a challenge because physical blend of an electron-donor and -acceptor in active layer can phase-separate into larger domains time. Copolymers that miscible with both donor acceptor stabilize morphology, but additives often tailored to match specific donor/acceptor blend. We demonstrate...
In dieser Zuschrift ist in Abbildung 1, oben rechts, die vertikale Achse inkorrekt mit δ anstelle Δδ beschriftet. Das korrigierte Diagramm hier gezeigt. […] Top right: nonlinear curve fitting of concentration-dependent NH chemical shift data (CDCl3) fit to an isodesmic model. Überdies als verwendetes Theorieniveau M06-2X/6-31+G* angegeben, richtig aber M06-2X/6-31G* (ohne diffuse Funktionen). Die Autoren entschuldigen sich für diese Versehen.
