9,9'-Dibromo-9,9'-bifluorene.

ABSTRACT: 9,9'-Dibromo-9,9'-bifluorene, C(26)H(16)Br(2), has a gauche conformation about the connecting C-C bond [the Br-C-C-Br torsion angle is 59.39?(16)°]. The crystal structure is sustained mainly by an inter-molecular C-Br?? inter-action [3.299?(2) and 3.369?(2)?Å] towards the bifluorene aromatic-ring-connecting C-C bond and a weak C-H?? inter-action (2.86 and 2.99?Å) between the two aromatic rings.

An unusual case of OD-allotwinning: 9,9′-(2,5-dibromo-1,4-phenylene)bis[9H-carbazole]

Project description:The title compound crystallizes as allotwins made up of two OD-polytypes with a maximum degree of order. 9,9′-(2,5-Dibromo-1,4-phenylene)bis[9H-carbazole] (1) crystallizes as a category I order–disorder (OD) structure composed of non-polar layers of one kind with B2/m(1)1 layer symmetry. The crystals are made up of the two polytypes with a maximum degree of order (MDO). The monoclinic MDO1 polytype (B21/d) possesses an orthorhombic B-centered lattice and appears in two orientations, which are related by reflection at (100). The orthorhombic MDO2 polytype (F2dd) has a doubled b-axis and appears in two orientations, which are related by inversion. The crystal structures of both polytypes were determined in a concurrent refinement. The MDO1:MDO2 ratio is 69:31.

Long and oriented graphene nanoribbon synthesis from well-ordered 10,10'-dibromo-9,9'-bianthracene monolayer on crystalline Au surfaces.

Project description:Bottom-up synthesis on metal surfaces has attracted attention for the fabrication of graphene nanoribbons (GNRs) with atomically-precise chemical structures to realize novel electronic devices. However, control of length and orientation on surfaces during GNR synthesis is difficult, thus, achieving longer and aligned GNR growth is a significant challenge. Herein, we report GNR synthesis from a well-ordered dense monolayer on Au crystalline surfaces for long and oriented GNR growth. Scanning tunneling microscopy showed that 10,10'-dibromo-9,9'-bianthracene (DBBA) precursors deposited on Au(111) at room temperature self-assembled into a well-ordered dense monolayer, and the straight molecular wire structure was formed where Br atoms in each precursor were adjacent along the wire axis. The DBBAs in the monolayer were found to be hardly desorbed from the surface under subsequent heating and efficiently polymerize along with the molecular arrangement, resulting in more long and oriented GNR growth compared to the conventional growth method. The result is attributed to be suppression of random diffusion and desorption of the DBBAs on the Au surface during polymerization due to the densely-packed DBBA structure. Additionally, an investigation of the effect of the Au crystalline plane on the GNR growth revealed further anisotropic GNR growth on Au(100) compared to Au(111) due to the stronger interactions of DBBA with Au(100). These findings provide fundamental knowledge for controlling GNR growth from a well-ordered precursor monolayer to achieve more long and oriented GNRs.

Synthesis of armchair graphene nanoribbons from the 10,10'-dibromo-9,9'-bianthracene molecules on Ag(111): the role of organometallic intermediates.

Project description:We investigate the bottom-up growth of N = 7 armchair graphene nanoribbons (7-AGNRs) from the 10,10'-dibromo-9,9'-bianthracene (DBBA) molecules on Ag(111) with the focus on the role of the organometallic (OM) intermediates. It is demonstrated that DBBA molecules on Ag(111) are partially debrominated at room temperature and lose all bromine atoms at elevated temperatures. Similar to DBBA on Cu(111), debrominated molecules form OM chains on Ag(111). Nevertheless, in contrast with the Cu(111) substrate, formation of polyanthracene chains from OM intermediates via an Ullmann-type reaction is feasible on Ag(111). Cleavage of C-Ag bonds occurs before the thermal threshold for the surface-catalyzed activation of C-H bonds on Ag(111) is reached, while on Cu(111) activation of C-H bonds occurs in parallel with the cleavage of the stronger C-Cu bonds. Consequently, while OM intermediates obstruct the Ullmann reaction between DBBA molecules on the Cu(111) substrate, they are required for the formation of polyanthracene chains on Ag(111). If the Ullmann-type reaction on Ag(111) is inhibited, heating of the OM chains produces nanographenes instead. Heating of the polyanthracene chains produces 7-AGNRs, while heating of nanographenes causes the formation of the disordered structures with the possible admixture of short GNRs.

9,9-Dimethyl-9-silafluorene.

Project description:The title compound, C(14)H(14)Si, crystallizes with two almost identical mol-ecules (r.m.s. deviation = 0.080?Å for all non-H atoms) in the asymmetric unit. All atoms of the silafluorene moiety lie in a common plane (r.m.s. deviations = 0.049 and 0.035?Å for the two mol-ecules in the asymmetric unit). The Si-C(meth-yl) bonds are significantly shorter [1.865?(4)-1.868?(4)?Å] than the Si-C(aromatic) bonds [1.882?(3)-1.892?(3)?Å]. Owing to strain in the five-membered ring, the endocyclic C-Si-C angles are reduced to 91.05?(14) and 91.21?(14)°.

2,2'-Bi(9,9-di-ethyl-fluorene).

Project description:The title compound, C34H34, systematic name 9,9,9',9'-tetra-ethyl-2,2'-bi(9H-fluorene), crystallized with two crystallographically independent mol-ecules (A and B) in the asymmetric unit. These differ mainly in the orientation of the lateral ethyl chains: in mol-ecule A, they are both on the same side of the mol-ecule whereas in mol-ecule B, one di-ethyl-fluorene moiety has undergone a 180° rotation such that the two pairs of ethyl residues appear on opposite sides of the mol-ecule. The fluorene ring systems subtend dihedral angles of 31.37 (4) and 43.18 (3)° in mol-ecules A and B, respectively. Hence the two fluorene moieties are tilted slightly toward one another. This may be due to the presence of inter-molecular C-H⋯π inter-actions between neighboring mol-ecules. The lateral ethyl chains (excluding H atoms) are also almost planar, with each pair almost perpendicular to the plane of the fluorene system to which they are attached with dihedral angles between the ethyl and fluorene planes in the range 86.04 (8)-89.5 (1)°.
