The synthesis and purification of amphiphilic conjugated donoracceptor block copolymers

Nanoscale domains of donor and acceptor materials are crucial for charge generation in organic photovoltaic devices. These domains are difficult to achieve reproducibly in blended materials, but could be engineered into single-material active layers composed of donor–acceptor block copolymers (BCPs). In this work, we report the synthesis and purification of two novel fully conjugated BCPs, P3HT...

Water dimer absorption of visible light

Laboratory measurements of water vapor absorption using cavity ring-down spectroscopy revealed a broad absorption at 405 nm with a quadratic dependence on water monomer concentration, a similar absorption with a linear component at 532 nm, and only linear absorption at 570 nm in the vicinity of water monomer peaks. D2O ab5 sorption is weaker and linear at 405 nm. Van’t Hoff plots constructed at...

Visible light-responsive micelles formed from dialkoxyanthracene-containing block copolymers.

A class of dialkoxyanthracene-containing diblock copolymers is synthesized which possesses visible light-responsivity. These copolymers can self-assemble into a micellar structure in water. Green visible light (540 nm) is able to scissor these anthracene species and cleave the diblock copolymer into two fragments, inducing disassembly of the self-assembled micelles.

Increasing visible-light absorption for photocatalysis with black BiOCl.

Black BiOCl with oxygen vacancies was prepared by UV light irradiation with Ar blowing. The as-prepared black BiOCl sample showed 20 times higher visible light photocatalytic activity than white BiOCl for RhB degradation. The trapping experiment showed that the superoxide radical (O(2)(•-)) and holes (h(+)) were the main active species in aqueous solution under visible light irradiation.

Visible-light-driven surface reconstruction of mesoporous TiO2: toward visible-light absorption and enhanced photocatalytic activities.

The surface structure of mesoporous TiO(2) is reconstructed via a visible-light-driven reaction with benzyl alcohol molecules at mild, anaerobic conditions, which substantially extends its visible-light absorption and photocatalytic activities.
