Acceptor-donor-acceptor small molecules containing benzo[1,2- b :4,5- b ']dithiophene and rhodanine units for solution processed organic solar cells

Synthesis, molecular geometry, spectroscopic studies and thermal properties of Co(II) complexes

“…Rhodanine azo dyes compounds are one of the most prevalent ligands in coordination chemistry. In addition to important roles in metal extracting agents, solar cells and biosensors . Because of the optical properties of azo dye compounds, one of the most important applications of azo compounds is in the optical data storage.…”

Ternary organic solar cells doped methoxyphenyl indenopyrazoloquinoline derivatives

“…A typical active layer is produced by blending conjugated polymers (donor) with high electron affinity molecules (acceptor), like fullerene derivatives. In principle we can consider two types of ternary solar cellsDonor 1: Donor 2: Acceptor and Donor: Acceptor 1: Acceptor 2 [13,14]. The publication concerns the active layer with two donors and one acceptor.…”

Synthesis, photophysical and electrochemical properties of a new star-shaped molecule with a 1,3,5-triethynylbenzene core and diketopyrrolopyrrole arms

“…Among many functional materials, the small conjugated organic molecule based materials have gained much attention because of their unique advantages of well-dened molecular structure, denite molecular weight, high purity, and better batch-to-batch reproducibility. [1][2][3] Such conjugated small molecules generally included linear molecules, 4,5 star-shaped molecules, 6,7 X-shaped molecules, 8 and dendritic molecules. 9 As is well known, the star-shaped small molecules of p-conjugated structure have displayed many outstanding advantages over linear conjugated small molecules such as monodispersity, excellent solubility as well as vast structures with different functional groups.…”
