Covalent organic frameworks (COFs) biphenyl ligands

As a ligand to synthesise COFs in application of OLEDs and porous materials


[1,1'-Biphenyl]-3,4',5-tricarbaldehyde (CAS number 187281-19-2) is a biphenyl derivative bearing three aldehyde groups. The positioning of the three aldehyde groups gives [1,1'-biphenyl]-3,4',5-tricarbaldehyde a C2V symmetric configuration. Taking the advantage of its unique symmetry, [1,1'-biphenyl]-3,4',5-tricarbaldehyde incorporates with hydrazine for the synthesis of a heteroporous COF. This heteroporous COF showcases two distinctively hexagonal pores, with sizes of 1.06 nm and 1.96 nm.

Additionally, [1,1'-biphenyl]-3,4',5-tricarbaldehyde reacts with a phosphonium salt of alkoxybenzene to prepare a hyperbranched poly(arylenevinylene) type COF (1,3,5-hb-PAV) via Wittig reaction. An OLED device (ITO/PEDOT:PSS/1,3,5-hb-PAV/Ca/Al) fabricated from the resulting COF exhibits maximum luminous efficiency of 2.1 Cd/A at 5 μA and a brightness of 22.4 Cd/m2.
