Transparent Organic Photodetector using a Near-Infrared Absorbing Cyanine Dye
Organic photodetectors are interesting for low cost, large area optical sensing applications. Combining organic semiconductors with discrete absorption bands outside the visible wavelength range with transparent and conductive electrodes allows for the fabrication of visibly transparent photodetectors. Visibly transparent photodetectors can have far reaching impact in a number of areas includin...
متن کاملCarbon Nanotubes as Near Infrared Radiation (NIR) Molecules for Cancer treatment
Introduction: The photo-thermal therapy by nanoparticles has been recently known as an efficient strategy for the cancer treatment. Carbon nanotubes (CNTs) have been extensively studied in biomedical application due to the easy uptake and high permeability in the cells, biocompatibility in biological environments and also their unique electrical, thermal properties. They genera...
متن کاملThe 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...

The facile synthesis of the new class of core-extended rylene chromophores, dibenzopentarylenebis(dicarboximide)s, having an intense absorption at 1020-1040 nm, is presented.
متن کاملNear-infrared dichromic fluorescent carbocyanine molecules.
Central to major advances in biochemical assays, molecular sensor technologies, and molecular optical imaging are fluorescent materials that provide high detection sensitivity for molecular processes. In biological optical imaging, the low tissue autofluorescence and the deep penetration of light into the tissues observed at wavelengths between 650 and 900 nm allow the use of near-infrared (NIR...
