“… Molecular aggregation is induced by adding a sufficient amount of diethyl ether as a poor solvent to the solution. The AIEE or CIEE properties of [DP-Im][Br] and [DP-Im][TFSI] are studied using solvent pair effects. − As shown in Figure S11, the PL intensities of [DP-Im][Br] and [DP-Im][TFSI] dissolved in a good solvent decreased upon increasing the volume fraction of the poor solvent. However, the solution containing 90% of the poor solvent is stirred for several hours, [DP-Im][Br] and [DP-Im][TFSI] are aggregated, and the suspension is formed.…”

A series of diketopyrrolopyrrole (DPP) luminogen amphiphiles were newly designed and synthesized by a single-step anionic exchange reaction for controlling the photoluminescence properties in both solution and solid states. Multicolor emission in response to thermal, mechanical, and chemical stimuli was successfully demonstrated by engineering well-defined supramolecular assemblies. Phase transformation from the metastable amorphous solid to the stable orthorhombic crystal of [DP-Im][Br] provided the reversibly patternable light emission. Selforganization into the smectic crystalline phase of [DP-Im][TFSI] allowed us to show the linearly polarized light emission. By simultaneously applying [DP-Im][Br] and [DP-Im][TFSI], we demonstrated the fabrication of smart sensors for packaging of food or vaccines that can detect thermal attacks.

“…FTIR spectroscopy can provide information about the noncovalent interactions of both polar and nonpolar groups through hydrogen bonding or dipole–dipole interactions [37,38,39,40]. Figure 4 presents the characteristic absorption signals for the (a) C=O units of MA-POSS, (b) C–H deformations of the CH 2 units of PVC, and (c) C–Cl stretching vibrations of PVC in various PVC/MA-POSS blends.…”

In this study, we investigated the influence of methacryl-functionalized polyhedral oligomeric silsesquioxane (MA-POSS) nanoparticles as a plasticizer and thermal stabilizer for a poly(vinyl chloride) (PVC) homopolymer and for a poly(vinyl chloride)/dissononyl cyclohexane-1,2-dicarboxylate (PVC/DINCH) binary blend system. The PVC and the PVC/DINCH blend both became flexible, with decreases in their glass transition temperatures and increases in their thermal decomposition temperatures, upon an increase in MA-POSS content, the result of hydrogen bonding between the C=O groups of MA-POSS and the H–CCl units of the PVC, as determined using infrared spectroscopy. Furthermore, the first thermal decomposition temperature of the pure PVC, due to the emission of HCl, increased from 290 to 306 °C, that is, the MA-POSS nanoparticles had a retarding effect on the decomposition of the PVC matrix. In tensile tests, all the PVC/DINCH/MA-POSS ternary blends were transparent and displayed flexibility, but their modulus and tensile strength both decreased, while their elongation properties increased, upon an increase in MA-POSS concentration, both before and after thermal annealing. In contrast, the elongation decreased, but the modulus and tensile strength increased, after thermal annealing at 100 °C for 7 days.

“…Finally, due to the interest in fluorescent-organic materials for optical applications in optoelectronic devices and as fluorescence sensors, polypeptides have been also studied for their photophysical properties. In particular, triphenyl pyridine-or triphenylamine-functionalized polytyrosine showed a similar aggregation-induced emission (AIE) behavior, which was explained as a consequence of the restriction of the intramolecular rotation mechanism for chromophoric compounds when attached to the polypeptides featured by a rigid-rod conformation [127,128].…”

From Prebiotic Chemistry to Supramolecular Biomedical Materials: Exploring the Properties of Self-Assembling Nucleobase-Containing Peptides

Peptides and their synthetic analogs are a class of molecules with enormous relevance as therapeutics for their ability to interact with biomacromolecules like nucleic acids and proteins, potentially interfering with biological pathways often involved in the onset and progression of pathologies of high social impact. Nucleobase-bearing peptides (nucleopeptides) and pseudopeptides (PNAs) offer further interesting possibilities related to their nucleobase-decorated nature for diagnostic and therapeutic applications, thanks to their reported ability to target complementary DNA and RNA strands. In addition, these chimeric compounds are endowed with intriguing self-assembling properties, which are at the heart of their investigation as self-replicating materials in prebiotic chemistry, as well as their application as constituents of innovative drug delivery systems and, more generally, as novel nanomaterials to be employed in biomedicine. Herein we describe the properties of nucleopeptides, PNAs and related supramolecular systems, and summarize some of the most relevant applications of these systems.
