Supramolecular Organic Frameworks of Brominated Bisphenol Derivatives with Organoamines

Reactions of two brominated bisphenol derivatives, tetrabromobisphenol-F (TBBPF) and tetrabromobisphenol-A (TBBPA), with various organoamines resulted in six supramolecular organic frameworks (SOFs), formulated as (TBBPF2–)2·(HPZ+)2·(H2PZ2+) (1), (TBBPF–)2·(H2PZ2+)·2H2O·2MeOH (2), (TBBPF)·(TBBPF–)·(HDABCO+)·H2O (3), (TBBPF)·(HMTA) (4), (TBBPA)·(HMTA) (5), and (TBBPA)3·(HMTA)3·H2O (6) (PZ = piperazine; DABCO = diazabicyclo[2.2.2]octane; HMTA = hexamethylenetetramine). Compounds 1–6 were characterized by single-crystal and powder X-ray diffractions. The predominant driving forces in 1–6 are hydrogen bonds (H-bonds), by which the compounds assemble into supramolecular organic frameworks with versatile topological structures. Compound 1 contains TBBPF/PZ in a 2:3 ratio and exhibits 2D (two-dimensional) H-bonded supramolecular 44-sql layer structure built by the four-connected {H2PZ2+} moieties and {TBBPF2–}. Compound 2 shows a 2-fold interpenetrated 3D (three-dimensional) H-bonded networks comprised by TBBPF/...
