The facile synthesis of a rotor-shaped compound with two stacked triazine units, which are symmetrically connected by three anthracene blades through oxygen linkers, is presented. This new double-decker, which is a potential monomer for two-dimensional polymerization, was synthesized by using readily available, cheap building blocks, exploiting the known selectivity difference for the nucleophilic substitution of cyanuric chloride. The crystal structure of a C3h symmetric rotor-shaped compound with 9,10-dihydroanthracene blades, which is a direct precursor to the targeted monomer, and the crystal structure of the new double-decker with the desired C3h symmetry, are also reported. The synthetic efforts were preceded by a computational analysis, which was triggered by the question of conformational stability of the potential monomer. Two stable conformers could be found, and the barrier for the transition path in the gas phase between these conformers was determined by quantum chemical calculations. Exploratory Born-Oppenheimer molecular-dynamics simulations revealed a strong influence of solvent-solute interactions on the stability of the conformers, which resulted in an energetic preference of the C3h symmetric conformation of the double-decker.

The invention discloses a fluorescent molecule for identifying mercury ions as well as a preparation method and application. Polycyclic aromatic hydrocarbons including a naphthalene ring or an anthracene ring and the like are used as starting raw materials and different identification sites are connected through a series of organic synthetic reaction (including substitution and addition) to obtainmolecular-tweezers-shaped main body compounds with different identification properties. The fluorescent molecule can be used for detecting the mercury ions and the problem that guest molecules cannotbe easily effectively identified through an existing molecule device is solved.

1,8-Ditriflated anthracene was prepared by an easy and straightforward approach that enables its reproducible synthesis on a 10 gram scale. Its symmetric/unsymmetric diethynylations by using the Sonogashira cross-coupling reactions were also demonstrated. Georg Thieme Verlag Stuttgart.
