In the title compound, [HgCl2(C16H28N2Se)], the primary geometry around the Se and Hg atoms is distorted trigonal–pyramidal and distorted square-pyramidal, respectively. The distortion of the molecular geometry in the complex is caused by the steric demands of the ligands attached to the Se atom. The Hg atom is coordinated through two chloride anions, an N atom and an Se atom, making up an unusual HgNSeCl2 coordination sphere with an additional long Hg...N interaction. Intermolecular C—H...Cl interactions are the only identified intermolecular hydrogen-bonding interactions that seem to be responsible for the self assembly. These relatively weak C—H...Cl hydrogen bonds possess the required linearity and donor–acceptor distances. They act as molecular associative forces that result in a supramolecular assembly along the b-axis direction in the solid state of the title compound.

Assembly Mechanism

Boron-dipyrromethenes (BODIPY) are promising functional dyes, whose exceptional optical properties are closely related to their supramolecular assembly. Herein, the self-assembly of a BODIPY derivative functionalized with uracil groups is explicitly and thoroughly investigated by using scanning tunneling microscopy (STM). Based on the simulation and calculation by density functional theory (DFT) method, it can be concluded that the construction of ordered self-assembly structure is attributed to the formation of hydrogen bonds between uracil groups. Moreover, the nanotribological property of the self-assembly on HOPG surface is measured by using atomic force microscopy (AFM). The effort on self-assembly of the BODIPY derivative could enhance the understanding of surface assembly mechanism.

Cis Isomer

Azobenzene-substituted tris(phenylisoxazolyl)benzene 1 was developed as a photoresponsive gelator. A detailed study of the self-assembly of the trans- and cis-isomers in solution revealed that the planar trans-isomer assembled to form molecular stacks along its C 3 axis, whereas the cis-isomer did not owing to steric requirements. Based on diffusion ordered spectroscopy experiments, the size of the aggregates formed from the trans-isomer were roughly four times as large as those of the cis-isomer. The photoinduced gel-to-sol transition was achieved by irradiation with UV light at 360 nm. Solid-state morphologies of the trans- and cis-isomers were quite contrastive; the trans-isomer created fibrous supramolecular networks with a lot of voids in which solvent molecules could be immobilized, whereas the cis-isomer never created such fibrous morphologies. The trans–cis structural change of the azobenzene moieties obviously regulates the gelation ability of 1.
