NIR-emitting aza-BODIPY dyes--new building blocks for broad-range optical pH sensors.
نویسندگان
چکیده
New aza-BODIPY indicators which cover the pH scale from 1.5 to 13 are presented. The new indicators feature absorption/emission bands in the red/near-infrared (NIR) spectral region, exhibit high molar absorption coefficients (∼ 80,000 M(-1) cm(-1)) and show good quantum yields (∼20%). All dyes represent promising building blocks for the development of a broad-range sensor for various pH ranges. Combination of four of these pH indicators yields a pH sensor with an extended dynamic range from pH 2 to 9.

Low cost referenced luminescent imaging of oxygen and pH with a 2-CCD colour near infrared camera.
A low cost imaging set-up for optical chemical sensors based on NIR-emitting dyes is presented. It is based on a commercially available 2-CCD colour near infrared camera, LEDs and tailor-made optical sensing materials for oxygen and pH. The set-up extends common ratiometric RGB imaging based on the red, green and blue channels of colour cameras by an additional NIR channel. The hardware and sof...
متن کاملThe Development of Novel Near-Infrared (NIR) Tetraarylazadipyrromethene Fluorescent Dyes
Novel structures of an near-infrared (NIR) tetraarylazadipyrromethene (aza-BODIPY) series have been prepared. We designed the core structure containing two amido groups at the para-position of the aromatic rings. The amido group was incorporated to secure insensitivity to pH and to ensure a bathochromic shift to the NIR region. Forty members of aza-BODIPY compounds were synthesized by substitut...
متن کاملNew insights into two-photon absorption properties of functionalized aza-BODIPY dyes at telecommunication wavelengths: a theoretical study.
Special attention has been paid to understanding the structural effect on electronic structure and absorption spectra for an extensive series of functionalized aza-BODIPY molecules. We have employed the quadratic response theory as well as a sum-over-states approach involving few intermediate states to calculate the two-photon cross section (δmax). The results suggest that chemical modification...

Series of novel dichromophoric cyanine dyes based on 2-aminobenzothiazoles and 3-amino-1,2,4 -triazole have been synthesized in high yields. All the dyes have been classified as disperse dyes. Besides their electronic spectroscopic properties, high dye-uptakes on polyester, excellent fastness properties, highly extinction coefficients, and broad solvatochromic effects have been observed in thes...
