General Description

2,2'-(1,4-Butanediyl)bis-1,3-benzoxazole is a chemical compound commonly used as an optical brightener and fluorescent whitening agent. It belongs to the class of benzoxazole compounds and is often found in laundry detergents, paper products, and plastics to enhance the whiteness and brightness of the materials. It works by absorbing ultraviolet light and re-emitting it as visible blue light, thereby making the materials appear whiter and brighter. 2,2'-(1,4-Butanediyl)bis-1,3-benzoxazole is also utilized in the textile and polymer industries for its light-stabilizing and UV-protective properties. Additionally, it has found applications in the manufacture of coatings, inks, and adhesives.

Different structures of two Cu(I) complexes constructed by bridging 2,2-(1,4-butanediyl)bis-1,3-benzoxazole ligand: Syntheses, structures and properties

Reaction of 2,2-(1,4-butanediyl)bis-1,3-benzoxazole (BBO) ligand with [Cu(CH3CN)2(PPh3)2][X] (X = ClO4, PF6) afforded a copper(I) coordination polymer (CP) {[Cu(BBO)(PPh3)]. ClO4}∞ (1) and a binuclear complex [Cu2(BBO)(PPh3)4]. 2PF6. 2CH2Cl2 (2) (where PPh3 = triphenylphosphine). Two complexes have been characterized. The structural analysis revealed that in complexes 1–2, all Cu(I) ions are tri-coordinated and the geometric structure around the central Cu(I) atom can be described as planar trigonal configuration. Complex 1 exhibits a one-dimensional coordination polymer by two BBO bridging adjacent copper(I) ions and extending along the b axis, forming a single-stranded helix chain structure that extends into 2-D layer frameworks through π…π interactions. Complex 2 shows a binuclear structure and the unit extends to a 2D supramolecular layered framework through C-H…F interactions. Moreover, compared with emissive bands of the free ligand in the solid state, the photoluminescent transition of the Cu(I) complexes 1–2 may be attributed to metal-to-ligand charge-transfer [MLCT].
