Diketopyrrolopyrrole-fullerene C60 architectures as highly efficient heavy atom-free photosensitizers: Synthesis, photophysical properties and photodynamic activity
(Royal Society of Chemistry, 2020-02)
Chromophore-fullerene C60 hybrids possess interesting properties that enable them to act as heavy atom-free photosensitizers and reactive oxygen species (ROS) producers. Here, two new diketopyrrolopyrrole-C60 conjugates ...
Gating That Suppresses Charge Recombination-The Role of Mono-N-Arylated Diketopyrrolopyrrole
(American Chemical Society, 2016-10)
Suppressing the charge recombination (CR) that follows an efficient charge separation (CS) is of key importance for energy, electronics, and photonics applications. We focus on the role of dynamic gating for impeding CR ...
Understanding the langmuir and Langmuir-Schaefer film conformation of low-bandgap polymers and their bulk heterojunctions with PCBM
(2020-07-31)
Low-bandgap polymers are widely used as p-type components in photoactive layers of organic solar cells, due to their ability to capture a large portion of the solar spectrum. The comprehension of their supramolecular ...

(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em QuímicaUTFPR, 2019-04-29)
The interest in the development of new materials that can be used in photovoltaic cells is increasing in the scientific scenario, due to the need to replace the energy matrixes derived from petroleum by renewable and clean ...
Estudo do espectro eletrônico da molécula ditienil-dicetopirrolopirrol com o uso da teoria do funcional da densidade dependente do tempo
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em QuímícaUTFPR, 2020-03-19)
Using the time-dependent density functional theory, the S0→S1 electronic spectrum of the 2,5-dihexyl-3,6-di(thiophen-2-yl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione molecule (DPP2T) was investigated, analyzing the performance ...
