Organocatalytic enantioselective synthesis of dihydronaphthofurans and dihydrobenzofurans: reaction development and insights into stereoselectivity
Susam, Zeynep Dilşad; Ozcan, Bilge Deniz; Kurtkaya, Enis; Yıldırım, Erol; Tanyeli, Cihangir (2022-10-01)
Squaramide/cinchona alkaloid-derived bifunctional organocatalysts are in high demand in asymmetric transformations. Bifunctional quinine-derived sterically encumbered squaramide (H-bond donor) organocatalysts were used to ...
Design Principles for the Acceptor Units in Donor-Acceptor Conjugated Polymers
Haciefendioglu, Tugba; Yıldırım, Erol (2022-10-01)
More than 50 different acceptor units from the experimental literature have been modeled, analyzed, and compared by using the computationally extracted data from the density functional theory (DFT) perspective for tetramer...
Side chain effect on the electrochemical and optical properties of thieno[3,4-c]pyrrole-4,6-dione based donor-acceptor donor type monomers and polymers
Çakal, Deniz; Demir Arabacı, Elif; Yıldırım, Erol; CİHANER, ATİLLA; Önal, Ahmet Muhtar (2022-09-01)
In organic pi-conjugated materials, side chains play great roles that impact far beyond solubility. In this work, we mainly focused on the synthesis of new donor-acceptor-donor (D-A-D) type conjugated monomers and their co...
