Photophysical and biological investigation of novel luminescent Ru(ii)-polypyridyl-1,8-naphthalimide Tröger's bases as cellular imaging agents
2012
Chemical Communications
The synthesis and photophysical properties of 1 and 2, two Ru(II)-polypyridyl based-1,8-naphthalimide Tro¨ger's bases, are described; these were found to stabilize double stranded DNA, undergo rapid cellular uptake, displaying good luminescence without affecting cell viability even after 24 hours of incubation. Scheme 1 The synthesis of the bis-Ru(II)polypyridyl naphthalimide complexes 1 and 2. (i) Paraformaldehyde, TFA. (ii) Ru(bpy) 2 Cl 2 , DMSO/H 2 O, microwave irradiation (See full experimental details in ESIw).
