Abstract
Understanding the molecular processes of nanowire self-assembly is crucial for designing and controlling nanoscale structures that could lead to breakthroughs in functional materials. In this work, we focus on pristine phthalocyanines as a representative example of mesogenic supramolecular assemblies and have analyzed the formation of nanowires using classical molecular dynamics simulations. In the simulations, the molecules spontaneously form multi-columnar structures resembling supramolecular polymers that subsequently grow into more ordered aggregates. These self-assemblies are concentration dependent, leading to the formation of multi-columnar, dynamic aggregates at higher concentrations and nanowires at lower concentrations. The multi-columnar assemblies on a whole are more disordered than the nanowires, but have locally ordered domains of parallel facing molecules that can fluctuate while maintaining their overall shape. The nanowire formation at lower concentrations involves the initial interaction and clustering of randomly oriented phthalocyanine molecules, followed by the merging of small clusters into elongated segments and the eventual formation of a stable nanowire. We observe three main conformers in these self-assemblies, the parallel, T-shaped and edge-to-edge stacking of the phthalocyanine dimers. We calculate the underlying free energy landscape and show that the parallel conformers form the most stable configuration which is followed by the T-shaped and edge-to-edge dimer configurations. The findings provide insights into the mechanisms and pathways of nanowire formation and a step towards the understanding of self-assembly processes in supramolecular mesogens.

Abstract
As an energy carrier, the phase change material can enhance the efficiency of an energy source and reduce its load. The present paper describes the assembly of the energy carrier molecule [stearic acid (SA)] into the interlayer spacing of montmorillonite (Mt). A novel inorganic/organic composite energy storage material was prepared, which effectively reduces the phase change temperature of the energy storage molecule. Through acid treatment, the Si4+/Al3+ ratio of Mt can be regulated to obtain a series of Mts with different layer charges. As a result, a controllable assembly of energy storage molecule, SA, into the interlayer spacing of Mts with different layer charges was accomplished. By controlling the layer charges of Mt arrangement morphology and interactive force of SA molecules in the interlayer, spacing of Mt can be changed effectively. The phase change temperature (exothermic reaction) reduces from 50.5 to 32 °C compared with the SA molecules, which are used to control phase change temperature of the energy storage material. The study presents a SA/Mt energy storage material that can aid in further development in the field of energy storage construction materials.

Abstract
Hexavalent chromium species, Cr(VI), which can activate teratogenic processes, disturb DNA synthesis and induce mutagenic changes resulting in malignant tumors. The detection and quantification of Cr(VI) is very necessary. One of the rapid and simple methods for contaminant analysis is fluorescence detection using organic dye molecules. Its application is limited owing to concentration quenching due to aggregation of fluorescent molecules. In this study, we successfully intercalated 7-amino-4-methylcoumarin (AMC) into the interlayer space of montmorillonite (MMT), significantly inhibited fluorescence quenching. Due to enhanced fluorescence property, the composite was fabricated into a film with chitosan to detect Cr(VI) in water. Cr(VI) can be detected in aqueous solution by instruments excellent, ranging from 0.005 to 100 mM with a detection limit of 5 μM.

Abstract
Diblock copolymer micelle nanolithography (BCML) is a versatile and efficient method to cover large surface areas with hexagonally ordered arrays of metal nanoparticles, in which the nanoparticles are equally spaced. However, this method falls short of providing a controlled allocation of such regular nanoparticle arrays with specific spacing into micropatterns. We present here a quick and high-throughput method to generate quasi-hexagonal nanoparticle structures with well-defined interparticle spacing on segments of nanotopographic Si substrates. The topographic height of these segments plays a dominant role in dictating the spacing between the gold nanoparticles, as the nanoparticle arrangement is controlled by immersion forces and by their self-assembly within the segments. Our novel strategy of employing a single-step BCML routine is a highly promising method for the fabrication of regular gold nanopatterns in micropatterns for a wide range of applications.

Abstract
Organic pigments such as indigos, quinacridones, and phthalocyanines are widely produced industrially as colorants for everyday products as various as cosmetics and printing inks. Herein we introduce a general procedure to transform commercially available insoluble microcrystalline pigment powders into colloidal solutions of variously sized and shaped semiconductor micro- and nanocrystals. The synthesis is based on the transformation of the pigments into soluble dyes by introducing transient protecting groups on the secondary amine moieties, followed by controlled deprotection in solution. Three deprotection methods are demonstrated: thermal cleavage, acid-catalyzed deprotection, and amine-induced deprotection. During these processes, ligands are introduced to afford colloidal stability and to provide dedicated surface functionality and for size and shape control. The resulting micro- and nanocrystals exhibit a wide range of optical absorption and photoluminescence over spectral regions from the visible to the near-infrared. Due to excellent colloidal solubility offered by the ligands, the achieved organic nanocrystals are suitable for solution processing of (opto)electronic devices. As examples, phthalocyanine nanowire transistors as well as quinacridone nanocrystal photodetectors, with photoresponsivity values by far outperforming those of vacuum deposited reference samples, are demonstrated. The high responsivity is enabled by photoinduced charge transfer between the nanocrystals and the directly attached electron-accepting vitamin B2 ligands. The semiconducting nanocrystals described here offer a cheap, nontoxic, and environmentally friendly alternative to inorganic nanocrystals as well as a new paradigm for obtaining organic semiconductor materials from commercial colorants.

Abstract
Quantum dot (QD) based micro-/nanopatterned arrays are of broad interest in applications ranging from electronics, photonics, to sensor devices for biomedical purposes. Here, we report on a rapid, physico-chemically mild approach to generate high fidelity micropattern arrays of prefunctionalized water-soluble quantum dots using electron beam lithography. We show that such patterns retain their fluorescence and bioaffinity upon electron beam lithography and, based on the streptavidin-biotin interaction, allow for detection of proteins, colloidal gold nanoparticles and magnetic microparticles. Furthermore, we demonstrate the applicability of QD based microarray patterns differing in their shape (circles, squares, grid-like), size (from 1 to 10 μm) and pitch distance to study the adhesion, spreading and migration of human blood derived neutrophils. Using live cell confocal fluorescence microscopy, we show that pattern geometry and pitch distance influence the adhesion, spreading and migratory behavior of neutrophils. Research reported in this work paves the way for producing QD microarrays with multiplexed functionalities relevant for applications in analyte sensing and cellular dynamics.

Metallophthalocyanines are well known to be of very good use in a wide range of applications. Nanomaterials based on this class of compounds could potentially have better qualities than the "parent" molecules. The electrochemical synthesis of cobalt phthalocyanine nanowires and the characterization using scanning electron microscope are presented. This is the first step towards a move to harnessing the potential of this class of nanomaterials for a wide range of new possible applications.

Abstract
The growth of one-dimensional (1D) fluorinated copper-phthalocyanine (CuPcF(16)) on gold (Au) nanoparticles (NPs) is studied by electron tomography. The shape of the 1D structure and its geometrical relationship with the associated Au NP are determined by a three-dimensional reconstruction analysis combined with high-resolution electron microscopy. The CuPcF(16) molecules nucleate at the <110> edge of the Au nanoparticle and grow parallel to a {111} facet of the particle along a direction close to <121>. This implies that the maximum diameter of the 1D structure is limited by the width of the <110> edge of the Au particle.
