A series of first (PG1) and second generation (PG2) dendronized polymers were synthesized which exhibit fast and sharp phase transitions with negligible hystereses in aqueous solutions and apparent lower critical solution temperatures (LCSTs) in the range of 33–49 °C.
The kinetic assembly pathways of a newly synthesized amphiphilic aza-BODIPY dye 1 were tuned by using H2O as a co-solvent in MeOH. Accordingly, the biphasic aggregation pathways resulting in kinetically-trapped and thermodynamically stable aggregates of 1 were established and the multiple cyclic seeded living supramolecularpolymerization of this dye was realized.
新合成的两亲性氮杂-BODIPY 染料1的动力学组装途径通过在 MeOH 中使用 H 2 O 作为共溶剂来调节。因此,建立了导致1的动力学捕获和热力学稳定聚集体的双相聚集途径,并实现了该染料的多环种子活性超分子聚合。

A well-defined nanofibrous structure with lengths of several hundred nanometers and cross-sectional width of a single size (similar to 6 +/- 0.5 nm) was self-assembled by oligoadenines, dA(20), and thymine-appended distyrylbenzene through binary complementary A-T hydrogen bond formation and the strong pi-pi stacking interactions. This demonstrated a useful supramolecular self-assembling approach to control the packing order of pi-conjugated molecules and provided a practical means to enhance the optical properties of a material.

The present invention relates to design and applications of a class of water-soluble small molecules represented by Formula 1. In aqueous solutions the said molecules exhibit lower critical solution temperature (LCST) phase transition near room temperature, imparting a temperature triggered switching of transparency stages. Further, it discloses a solution comprising Formula 1 and a scalable smart radiative energy management system that takes form of a dynamic window, wherein the aqueous solution is sandwiched between two transparent glass panes to enable modulation of light and heat transmission. With simple and economical starting materials, the dynamic windows of present invention represent leaps towards creating a niche technology with multifarious applications in developing scalable, smart energy management systems for indoor building environments.
