Four generations of new amphiphilic thermoresponsive linear-dendritic block copolymers (LDBCs) with a linear poly(N-vinylcaprolactam) (PNVCL) block and a dendritic poly(benzyl ether) block are synthesized by atom transfer radical polymerization (ATRP) of N-vinylcaprolactam (NVCL) using dendritic poly(benzyl ether) chlorides as initiators. The copolymers have been characterized by 1H NMR, FTIR, and GPC showing controlled molecular weight and narrow molecular weight distribution (PDI ≤ 1.25). Their self-organization in aqueous media and thermoresponsive property are highly dependent on the generation of dendritic poly(benzyl ether) block. It is observed for the LDBCs that the self-assembled morphology changes from irregularly spherical micelles, vesicles, rod-like large compound vesicles (LCVs), to the coexistence of spherical micelles and rod-like LCVs, as the generation of the dendritic poly(benzyl ether) increases. The results of a cytotoxicity study using an MTT assay method with L929 cells show that the LDBCs are biocompatible.

A total synthesis of curvulone B has been completed using a Friedel-Crafts reaction and a highly cis-selective intramolecular oxa-Michael addition. The 2-chlorobenzyl protecting group was employed and found to have much greater Lewis acid stability compared to the simple benzyl group.

We report, for the first time, an in situ formation of two-component hydrogels from pyridine derivatives of poly(aryl ether) dendrons and tartaric acid. The two-component system (dendron + acid) undergoes J-type aggregation, leading to fibrillar type self-assembly in THF-water mixture along with blue (470 nm) and green (500 nm) intrinsic emissions.
