Effects of heteroatom substitution in conjugated heterocyclic compounds on photovoltaic performance: from sulfur to tellurium.
We report a general strategy for fine-tuning the bandgap of donor-acceptor-donor based organic molecules by modulating the electron-donating ability of the donor moiety by changing the benzochalcogenophene donor groups from benzothiophenes to benzoselenophenes to benzotellurophenes. These molecules show red-shifts in absorption and external quantum efficiency maxima from sulfur to selenium to t...
متن کاملSYNTHESIS AND THERMAL REARRANGEMENT OF OXYGEN HETEROCYCLIC SPIRANS
Thermal rearrangement of spirans (14) and (31) yields the xanthones (16,34) and diphenylrnethane (15, 32), respectively. The structure for xanthone (16), isolated from thermolysis, has been established by reduction to xanthene (20) followed by reoxidation to give xanthone (16). Alternatively, methylation of the diphenylmethane (15) followed by heating with selenium dioxide also yields xant...

متن کاملOne-photon ionization spectroscopy of jet-cooled oxazole and thiazole: the role of oxygen and sulfur in the pi-conjugation of heterocyclic compounds.
One-photon mass-analyzed threshold ionization (MATI) spectroscopy of jet-cooled oxazole and thiazole has been carried out to give the precise adiabatic ionization energies of 9.5959+/-0.0006 and 9.3633+/-0.0009 eV, respectively. The structural change upon ionization has been revealed in the vibrationally resolved one-photon MATI spectra. Simulations based on the Franck-Condon analysis using the...
متن کاملSynthesis of oxygen-containing heterocyclic compounds based on the intramolecular O–H insertion and Wolff rearrangement of a-diazocarbonyl compounds
The addition products of Ti(IV)-enolate derived from b-keto a-diazo carbonyl compound to ketones or a,b-unsaturated compounds were subjected to Rh2(OAc)4-catalyzed and photo-induced diazo decomposition. The Rh2(OAc)4-catalyzed reaction afforded intramolecular O–H insertion products, while the photo-induced reaction gave Wolff rearrangement/intramolecular nucleophilic addition products. The tran...
