Aggregation-induced emission from the crowded coronal chains of block copolymer micelles

Abstract

<p>Aggregation-induced emission (AIE) was triggered <italic>via</italic> the spatial confinement in the coronal chains in block copolymers upon micellization, even with very low content of AIE groups attached, and this could be used to monitor the self-assembly process.</p>

Density‐Dependent Emission Colors from a Conformation‐Switching Chromophore in Polyurethanes

“…This result suggested that this color-varying process is caused not only by the conformation switching from tricoordinated state to tetracoordinated state, but also the solvatochromic effect of BCD molecule due to its D-p-A feature.Also,those findings were clearly distinguished from aggregation-induced emission mechanisms. [15] Consequently,atheoretical modeling on the aggregation state of the molecule was carried out to provide amechanistic understanding of this color-switching phenomenon on the molecular level. Thet wo hexan-1-ol side chains on Na tom were replaced with methyl groups to simplify the simulation of the chromophore (namely BCD*).…”

Self-sorting assembly of artificial building blocks

“…Apart from the examples presented above, other orthogonal supramolecular interaction pairs were also well explored, including hydrophobic interaction/high affinity between fluorinated moieties, 96 hydrogen bond/hydrophobic interactions, 97 hydrogen bond/coordination bonds, 61,98 and hydrogen bond/π–π interaction. 99 Meanwhile, some other strong interactions or driving forces could also be combined and utilized for constructing self-sorting systems, including crystallization of small molecules and macromolecules, 16 liquid crystalline ordering-driven assembly, 17,100–104 etc.…”

Versatile, stable, and air-tolerant triplet–triplet annihilation upconversion block copolymer micelles

“…[37][38][39] In particular, block copolymer micelles with nicely adjusted dimensions and morphologies may provide an additional control over photoluminescence behaviours. 40,41 Herein, we report a block copolymer micellization approach toward a versatile, stable, and highly air-tolerant TTA-UC system. A diblock copolymer containing a corona-forming block poly(tert-butyl acrylate) (PtBA), which is soluble in various organic solvents, and a core-forming block from DPAcontaining methacrylate monomers (PDPAMA) was synthesized via atom transfer radical polymerization (ATRP).…”
