Source of material

1,8-Diiodoanthracene (430 mg, 1 mmol) was placed in a 50 ml Schlenk flask along with 4-ethynylpyridine hydrochloride (278 mg, 2 mmol), (Ph3P)2–PdCl2 (10 mg), and CuI (2 mg). Diethylamine (40 ml) was distilled under nitrogen directly into the reaction flask, and the reaction was stirred in the dark at room temperature for 2 days. The solvent was then removed in vacuo; the residue was redissolved in dichloromethane, washed with water, and then washed with brine. The organic fraction was dried with Na2SO4, filtered through a silica gel plug, and then the solvent was removed on a rotary evaporator to produce 1,8-bis(4-pyridylethynyl)anthracene as a yellow solid. A mixture of 1,8-bis(4-pyridylethynyl)anthracene (380 mg, 1.0 mmol) and 1,3-bis(bromomethyl)benzene (262 mg, 1.0 mmol) in CH3CN (300 ml) was stirred for 24 h at reflux under nitrogen atmosphere. Then, the mixture was filtrated, washed with acetone, and dried in vacuo and by protonation the title compound was obtained (635.1 mg, 0.82 mmol) as a yellow solid. Crystals of the title compound were obtained by slow vapor diffusion of ether to a solution of title compound in CH3CN within 1 weeks.

Experimental details

Hydrogen atoms were placed in their geometrically idealized positions and constrained to ride on their parent atoms.

Comment

Efficient synthesis of novel macrocyclic hosts with unique structures and good host–guest properties is a permanent and challenging topic in the field of supramolecular chemistry [3], [4], [5]. During the last decade, considerable effort has been devoted to the development of macrocyclic molecular and a number of new macrocyclic receptors with novel properties have been reported, such as pillar[n]arene [6, 7], Ex-box [8], and others [9]. These approaches often suffer from long synthetic steps and low yields, which restrict their further application in the complicated supramolecular self-assembly. Recently, we reported the high yield synthesis of a novel good water-soluble macrocycle containing two pyridinium moieties [10].

The title compound will enriched the toolbox of supramolecular chemists. The single-crystal structure verifies that all bond lengths are in normal ranges.
