Enhanced photooxidation sensitizers: the first examples of cyclometalated pyrene complexes of iridium(III).
The iridium(III) cyclometalation of alkylated pyrene-benzimidazole ligands proceeds in an unprecedented manner. The resultant complexes display remarkably enhanced photooxidation capabilities using 1,5-dihydroxynaphthalene as a substrate.

در این تحقیق روشی جهت سنتز یک سری از کمپلکس های پلاتین (ii) حاوی لیگاند های دهنده ی فسفری شامل فسفیت و فسفین ارائه شده است. واکنش پیش ماده ی پلاتین (ii)،trans/cis- [ptcl2(sme2)2] ، با 2 اکی مولار از لیگاند p(oph)3در حلال بنزن کمپلکس1، cis-[ptcl2(p(oph)3)2] را تولید می نماید. جهت سنتز کمپلکس سایکلو متال فسفیتی، کمپلکس 1 با 1 اکی والان واکنشگر ptcl2 در حلال زایلن در شرایط رفلاکس زیر گاز آرگون م...
Visible-light harvesting iridium complexes as singlet oxygen sensitizers for photooxidation of 1,5-dihydroxynaphthalene.
Visible-light harvesting cyclometalated Ir(III) complexes were used as (1)O(2) sensitizers for the photooxidation of 1,5-dihydroxynaphthalene (DHN) and substantially improved photooxidation capability was observed compared to the conventional Ir(III) complex sensitizers that show no visible light-harvesting capabilities.
متن کاملPhotooxidation of 1,5-dihydroxynaphthalene with iridium complexes as singlet oxygen sensitizers.
Photooxidation reactions of 1,5-dihydroxynaphthalene (DHN) have been carried out in the presence of cyclometalated neutral and cationic iridium (Ir) complexes 1-6 as singlet oxygen ((1)O(2)) sensitizers in order to investigate the (1)O(2) generation quantum yield and photosensitizing durability of the complexes. The reactions allowed a successful kinetic study to provide the pseudo-first-order ...
