Synthesis of Ru(ii) and Os(ii) photosensitizers bearing one 9,10-diamino-1,4,5,8-tetraazaphenanthrene scaffold

Abstract

The synthesis of eight Ru(II) and Os(II) photosensitizers bearing a common 9,10-disubstituted-1,4,5,8-tetraazaphenanthrene backbone is reported. With Os(II) photosensitizers, the 9,10-diNH2-1,4,5,8-tetraazaphenanthrene could be directly chelated onto the metal center via the...
