Article
Full-text available
We report a comparative study of two structurally similar donor-acceptor complexes with (1a) and without (2a) H-bonding using X-ray crystallography, spectroscopic analysis, and density functional theory calculations. H-Bonding enhances the donor-acceptor interactions, as manifested in a narrower band gap and shorter π-stacking distance in 1a versus...
Article
Full-text available
We report a detailed investigation of a series of new charge-transfer (CT) complexes assembled via a two-point complementary hydrogen bonding (H-bonding) of diindolopyrrole (DIP) electron donors with o-quinone and diazafluorenone acceptors. Unidirectional polarization through the DD⋯AA type H-bonding leads to a dramatic perturbation of electronic l...
Article
We report the serendipitous discovery and synthesis of an indigoid “Semi-Nindigo” (2) via oxidation of a diindolopyrrole (1). Reaction of 2 with BF3Et2O affords the borylated derivate (3). The electronic spectra of 2 and 3 possess intense long wave absorptions near 600 nm and 650 nm. 3 is weakly emissive in the near-infrared. Thin film OFETs fabric...
Article
A comprehensive investigation of the complementary H-bonding-mediated self-assembly between dipyrrolo[2,3-b:3′,2′-e]pyridine (P2P) electron donors and naphthalenediimide/perylenediimide (NDI/PDI) acceptors is reported. The synthesis of parent P2P and several aryl-substituted derivatives is described, along with their optical, redox, and single-crys...
Article
New poly(ethylene oxide)-based block copolymers (ssBCs) with a random copolymer block consisting of a reduction-responsive disulfide-labeled methacrylate (HMssEt) and a thermoresponsive di(ethylene glycol)-containing methacrylate (MEO2MA) units were synthesized. The ratio of HMssEt/MEO2MA units in the random P(MEO2MA-co-HMssEt) copolymer block enab...
Article
The synthesis, tunable thermoresponsive properties, and self-assembly of dual redox and thermoresponsive double hydrophilic block copolymers having pendant disulfide linkages (DHBCss) are reported. Well-defined DHBCss composed of a hydrophilic poly(ethylene oxide) block and a dual thermo- and reduction-responsive random copolymer block containing p...
