Covalent Organic Frameworks (COFs) Fumaronitrile Ligand

A dibromo bridging ligand linker for COFs in application of OLEDs and small molecule organic solar cells (SMOSCs)

Specifications | MSDS | Literature and Reviews

2,3-Bis(4-bromophenyl)fumaronitrile, CAS number 82193-93-9, belongs to the fumaronitrile family with two 4-bromophenyls replacing the hydrogens on the double bond.

2,3-Bis(4-bromophenyl)fumaronitrile and 4-(carbazol-9-yl)phenylboronic acid via C-C coupling reaction gave stimuli-responsive fluorophoric molecule 2,3-bis[4'-(9-carbazolyl)-(1,1'-biphenyl)-4-yl]-2-butenedinitrile. The molecule demonstrated emission colour switching between green and orange in the solid state upon grinding, heating, and exposure to chemical vapor. NIR fluorescent compound 2,3-bis(4′-(diphenylamino)-[1,1′-biphenyl]-4-yl)fumaronitrile (TPATCN) with a fumaronitrile component, showed a relatively large dipole moment of the charge transfer state. Device based on TPATCN exhibited strong NIR fluorescence with thin film quantum efficiency of 33% and crystal efficiency of 72%. An external quantum efficiency of 2.58% was recorded for non-doped NIR organic light-emitting diode (OLED) device based on TPATCN.

Organic π-conjugated semiconducting chromophore, RCNR, based on alkylated bithiophene terminated fumaronitrile-core acceptor, showed a broad absorption peak near green region and strong emission peak in red due to the strong electron-withdrawing nature of two nitrile (–CN) groups. Fabricated SMOSC devices with RCNR:PC60BM (1:3, w/w) active layer exhibited a power conversion efficiency of 2.69%.
