Abstract
Water-soluble quantum dots (QDs) are necessary to prepare patterned pixels or films for high-resolution displays with less environmental burden but are very limited by the trade-off between photoluminescence and stability of QDs. In this work, we proposed synthesizing water-soluble QDs with simultaneous excellent luminescence properties and high stability by coating the amphiphilic poly(maleic anhydride-alt-1-octadecene)-ethanol amine (PMAO-EA) polymer on the surface of silane-treated QDs. These coated QDs show a photoluminescence quantum yield (PLQY) as high as 94%, and they have good photoluminescence stability against light irradiation and thermal attacks, owing to the suppression of the nonradiative recombination by the polymer layer and the isolation of oxygen and water by the silica layer. The water-soluble QDs, mixed with ethylene glycol, enable inkjet printing of QD color conversion films (QD-CCFs) with an average diameter of 68 μm for each pixel and a high PLQY of 91%. The QD-CCFs are demonstrated to fabricate red-emitting mini-LEDs by combining with blue mini-LED chips, which have an external quantum efficiency as high as 25.86% and a luminance of 2.44 × 107 cd/m2. We believe that the proposed strategy is applicable to other water-soluble QDs and paves an avenue for inkjet printing environmentally friendly QD-CCFs for mini/micro-LED displays.

Abstract
Small molecule gelators are serendipitously discovered more often than they are designed. As a consequence, it has been challenging to develop applications based on the limited set of known materials. This synopsis highlights recent strategies to streamline the process of gelator discovery, with a focus on the role of unidirectional intermolecular interactions and solvation. We present these strategies as a series of tools that can be employed to help identify gelator scaffolds and solvents for gel formation. Overall, we suggest that this guided approach is more efficient than random derivatization and screening.

Abstract
For years researchers have tried to understand the molecular behavior of complex biomolecules through the development of small molecules that can partially mimic their function. Now researchers are implementing the reverse approach: using the structural and mechanistic knowledge obtained from those complex systems to design small molecules with defined properties and for specific applications. One successful strategy for constructing bioinspired, minimalistic molecules is to combine natural building blocks that provide functional elements with abiotic fragments that serve as structural scaffolds. Therefore pseudopeptidic compounds, most of them based on C2 symmetric structures, represent a unique opportunity to explore and evaluate this approach. Some of these molecules are as simple as two amino acids connected by a diamino spacer. The results in this Account show how bioinspired minimalistic pseudopeptides can form ordered structures, participate in the recognition and transcription of information events in molecular devices, and catalyze reactions. This strategy allows researchers to design and prepare a variety of open-chain and macrocyclic compounds leading to systems that can self-aggregate to form hierarchically ordered micro- and nanostructures. In addition, small changes in the molecule or external stimuli can regulate the self-aggregation pattern. In the same way, researchers can also tune the molecular movements of simple pseudopeptides through environmental factors, providing a means to control new molecular devices. In addition, some of the prepared model compounds have shown interesting properties in molecular recognition and even as sensors for several targets of interest. Finally we have observed remarkable catalytic activities from these types of molecules, although those results are still far from the efficiency shown by natural peptides. This family of pseudopeptidic compounds offers the opportunity for the more elaborate design of relatively simple abiotic but bioinspired systems that display specific properties. In addition, the results can provide additional information that will increase the molecular understanding of the basic principles that underlie the extraordinary behavior of natural systems.

Abstract
In this work, the triplet state behavior of naphthalene-based pseudopeptides with amide-based macrocyclic or lateral chain substructures has been investigated in the presence of benzophenone and/or biphenyl, as suitable energy-donating chromophores. Their behavior has been compared with that of 1,4-dimethylnaphthalene as model compound. In all the cases, the triplet-triplet absorption of naphthalene is detected by transient absorption spectroscopy, upon selective excitation of benzophenone at 355 nm. The kinetics of formation and decay of this species is markedly slower in the pseudopeptides, due to retardation of triplet-triplet energy transfer and exciplex formation. Finally, the delayed fluorescence detected in the model naphthalene is absent in the pseudopeptides. The concept can, in principle, be exploited for the study of excited-state interactions in supramolecular systems.
