Alkali lignin (AL) was used as a polyanion to form layer-by-layer self-assembled film with PDAC as a polycation. The effects of temperature and concentration on the adsorption characteristics of AL were investigated. Iodine was added into AL solutions to study the role of π-π interaction in self-assembly of AL and PDAC. Results show that the self-assembly of AL/PDAC is mainly driven by π-π interaction and electrostatic interaction. A higher temperature or a larger concentration can enhance the aggregation of lignin. I2 can form lignin–iodine charge–transfer complexes with AL to reduce the degree of aggregation of AL, so the adsorbed amount of AL decreases significantly with increasing iodine contents.

The controlled engineering of functional architectures composed of π-systems with unusual opto-electronic properties is currently being investigated intensively from both fundamental research and technological application viewpoints. In particular, the exploitation of the supramolecular approach for the facile construction of multidimensional architectures, featuring cavities capable of hosting functional molecules, could be used in several applications, such as nanomedicine, molecular-based memory storage devices, and sensors. This paper highlights our recent strategies to use hydrogen-bonding interactions to prepare nanostructured functional architectures via the self-assembly of organic molecular modules studied at different interfaces.

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.
