Overview
Related Products

4',4''',4'''''-Nitrilotris([1,1'-biphenyl]-4-carbaldehyde) (NTBCA), CAS number 872689-79-7, has a triangular structure with triarylamine core and three aldehyde functional groups. The triarylamine core is electron rich and the aldehyde groups condense with amines to form imine linkages in covalent organic framework (COFs).

Covalent organic framework HAT-NTBCA-COF, featuring [C6 + C3] symmetric units of propeller-like hexaamino-hexaazatriphenylene ([NH₂]₆HAT) nodes and triangular symmetric linker NTBCA with imine linkages showed high thermal stability with CO₂ uptakes of HAT-NTBCA-COF being 6.0 wt% (273 K) and 3.7 wt% (298 K).

[3 + 4] condensation reaction forming imine linkages between triangular 4′,4′″,4′″″-nitrilotris([1,1′-biphenyl]-4-carbaldehyde) with rectangular 4,4′,4″,4′″-(ethene-1,1,2,2-tetrayl)tetraaniline gave COF-1. With great thermal and chemical stability, COF-1 served as efficient photocatalyst for the cross-dehydrogenative coupling reaction and also the asymmetric α-alkylation of aldehydes integrated with a MacMillan imidazolidinone as the chiral catalyst under visible light.
