Highly reversible photochromism in composite WO3/nanocellulose films

Reversible photochromism of polynorbornenes bearing spiropyran side groups

ABSTRACT In this paper, the synthesis and characterization of poly(norbornene) homo- and copolymers bearing spiropyran side groups are described. Difficulties in the homopolymerization of spiropyrans due to the opened merocyanine form were observed leading to low polymerization yields for homopolymers while copolymers with 10 mol% spiropyran content were prepared in good yield. Spiropyrans are ...

Ultrastable, Highly Luminescent Organic-Inorganic Perovskite-Polymer Composite Films.

A simple yet general swelling-deswelling microencapsulation strategy has been developed to achieve well dispersed and intimately passivated crystalline organic-inorganic perovskites nanoparticles within polymer matrixes and results in a series of highly luminescent CH3 NH3 PbBr3 (MAPbBr3 )-polymer composite films with unprecedented water and thermal stabilities and superior color purity.
