Mol. self-assembly on surfaces is driven by the range of interactions between the mols. themselves and the substrate. Generally, a face-on structure is favored for aromatic mols. lying flat on the surface. Here, the authors report on the supramol. self-assembly of 5,10,15,20-tetrakis(10-bromoanthracen-9-yl)porphyrin on the Ag(111) and Ag(110) surfaces. Well-ordered mol. chains were observed by room-temperature scanning tunneling microscopy on both surfaces. The relatively small size of the unit cell revealed an edge-on configuration of the porphyrin macrocycles, i.e., perpendicular to the surface plane, as confirmed by mol. mechanics calculations Distinct intermol. interactions were found on the 2 surfaces, providing different mol. chain orientations on Ag(111) and Ag(110). The experimental part of the paper was very detailed, including the reaction process of 9,10-Dibromoanthracene(cas: 523-27-3Synthetic Route of C14H8Br2)
9,10-Dibromoanthracene(cas: 523-27-3) is a dibrominated polycyclic aromatic hydrocarbon (PAH). 9,10-Dibromoanthracene is often used as an energy acceptor and activator in reactions that produce chemiluminescence.Synthetic Route of C14H8Br2
