An exceptionally long-lived triplet state of red light-absorbing compact phenothiazine-styrylBodipy electron donor/acceptor dyads: a better alternative to the heavy atom-effect?

Chemical Communications, 2020
A series of phenothiazine-styrylborondipyrromethene compact electron donor/acceptor dyads were prepared to access heavy-atom-free triplet photosensitizers showing red-absorption and especially long-lived triplet states (303 μs), based on the spin orbital

Visible-to-Near-Infrared Light-Driven Photocatalytic Hydrogen Production Using Dibenzo-BODIPY and Phenothiazine Conjugate as Organic Photosensitizer

ACS Applied Energy Materials, 2019
A novel visible-to-near-infrared (visible-to-NIR) light-driven photocatalyst was prepared by loading a dibenzo-BODIPY-phenothiazine conjugate dye 1 as a panchromatic photosensitizer on hierarchical porous TiO2 (HPT) semiconductor. The sensitizer 1, which

PHENOTHIAZINE

Journal of the American Medical Association, 1943
Our interest in phenothiazine as an anthelmintic agent was stimulated by Manson-Bahr's report 1 on its effectiveness in threadworm and roundworm infections in man. An additional stimulus was provided by the preliminary report of the Council on Pharmacy and Chemistry, 2 which stated that phenothiazine 3 had interesting possibilities and that further ...
