Abstract
Hierarchical assemblies from block copolymer (BCP)-based supramolecules have shown immense potential as programmable materials owing to their versatility for incorporating functional molecules and provide access to arrays of hierarchical structures. However, there remains a knowledge gap on the formation of the supramolecule in solution. Here, we applied NMR techniques to investigate the solution-phase behavior of the most studied supramolecular systems, polystyrene-block-poly(4-vinylpyridine)(3-pentadecylphenol) (PS-b-P4VP(PDP)r). The results show that the supramolecule likely adopts a coil-comb conformation, despite the small molecule's (PDP) rapid exchange between the bonded and free states. The exchange rate (>104 s-1) exceeds the NMR time scale at the frequency of interest. The supramolecules form under dilute conditions (∼2 vol %) and are attributed to the enthalpic gain of the hydrogen bonding between the PDP and 4VP. As the solute concentration increases (>10 vol %), the supramolecule forms micelle-like aggregates with PDP accumulated within the comb-block's pervaded volume based on analysis of the apparent molecular weight, viscosity, and chain dynamics. This work sheds light on the long-standing question regarding the evolution of the constituents in the BCP-based supramolecule in solution and provides valuable guidance toward their solution-based processing and morphological control.

Abstract
The interactions between hexafluoroisopropanol (HFIP) and halogen anions X- (F-, Cl-, Br-, and I-) have been investigated using negative ion photoelectron (NIPE) spectroscopy and ab initio calculations. The measured NIPE spectrum of each [HFIP·X]- (X = Cl, Br, and I) complex shows a pattern identical to the corresponding X- by shifting to the high electron binding energy side, indicative of the formation of the [HFIP···X-] structure in which X- interacts with HFIP via charge-dipole interactions. However, the spectrum of [HFIP·F]- appears completely different from that of F- and is more similar to the spectrum of the deprotonated HFIP anion (HFIP-H-). The geometry and electron density calculations indicate that a neutral HF molecule is formed upon HFIP interacting with F- via proton transfer, rendering a stable structure of [HFIP-H···HF]-. Two conformers of [HFIP-H·HF]- with HFIP being in synperiplanar and antiperiplanar configurations, respectively, are observed, providing direct experimental evidences to show the distinctly different and orientation-specific interactions between HFIP and halide anions.

Abstract
The PVP and its derivatives have been broadly applied in polymers, organic
syntheses, and catalysis processes. The crosslinked PVP is a well-known polymer support
for numerous reagents and catalysts. Cross-linked PVPs are commercially available polymers
and have attracted much attention over the past due to their interesting properties
such as the facile functionalization, high accessibility of functional groups, being nonhygroscopic,
easy to prepare, easy filtration, and swelling in many organic solvents. A
brief explanation of the reported applications of PVPs in different fields followed by the
discussion on the implementation of methodologies for catalytic efficiency of PVP-based
reagents in the organic synthesis is included. The aim is to summarize the literature under
a few catalytic categories and to present each as a short scheme involving reaction conditions.
In the text, discussions on the synthesis and the structural determination of some typical polymeric reagents
are presented, and the mechanisms of some organic reactions are given. Where appropriate, advantages
of reagents in comparison with the previous reports are presented. This review does not include patent literature.
