Transfer of chirality from light to a Disperse Red 1 molecular glass surface
(Optical Society of America, 2017-08-30)
Chiral structures and materials interact with light in well-documented ways, but light can also interact with achiral materials to generate chirality by inscribing its asymmetric configuration on photoresponsive materials, ...
Towards amorphous solution-processed small-molecule photovoltaic cells by design
Organic photovoltaic cells incorporating a homogeneously blended amorphous active layer were fabricated using a novel glass-forming squarylium cyanine derivative (SQ-glass) as donor, and both a previously reported glass-forming ...
Efficiency enhancement of ternary blend organic photovoltaic cells with molecular glasses as guest acceptors
Previously reported glass-forming perylenediimide (PDI-glass) and diketopyrrolopyrrole (DPP-glass) acceptors were used as ternary components to modulate the morphology and electron transport properties of bulk heterojunctions ...
Simple Unbiased Hot-electron Polarization-sensitive Near-Infrared Photo-detector
(American Chemical Society, 2018-03-06)
Plasmonic nanostructures can generate energetic “hot” electrons from light in a broad band fashion depending on their shape, size, and arrangement. Such structures have a promising use in photodetectors, allowing high ...
Solid-state showdown: comparing the photovoltaic performance of amorphous and crystalline small-molecule diketopyrrolopyrrole acceptors
A novel glass-forming diketopyrrolpyrrole (DPP) derivative (DPP-glass) and a crystalline isoelectronic analogue were synthesized and their photophysical, electrochemical and photovoltaic properties were investigated. The ...
Deceleration of thermal ring closure in a glass-forming mexylaminotriazine-substituted merocyanine (MC) linked to intramolecular hydrogen bonding
The design and synthesis of a glass-forming nitrobenzospiropyran (SP) functionalized with a mexylaminotriazine group is reported herein. The title compound was synthesized in 63% overall yield by the carbamylation of a ...
